FAQ : Your most frequently asked questions

The concept and technology

A menstrual panty is an undergarment that, thanks to an absorbent zone, acts as both lingerie and
hygienic protection! With our innovative technology, you no longer need to use tampons, menstrual cups, or
sanitary napkins, our menstrual panties are self-sufficient. However, nothing prevents you from using both at the same time
if you wish.

To know more about it, don't hesitate to make a tour on our page "The concept".

To be serene and to limit the number of machines throughout your cycle, we recommend that you have at least 3 pairs of period underwear, including at least one model for heavy to very heavy flow, special "long duration" to last through the night.

Our ELIA undergarments are perfectly suited for the challenges of your three trimesters and for postpartum. Our Louison cyclist is specifically designed for postpartum.

Our panties are slightly thicker than regular lingerie, to allow for the absorbent and waterproof zone to be inserted between our two cotton layers. However, they are not as thick as conventional sanitary napkins, making them a very comfortable and pleasant undergarment to wear. The design of our seams also makes them invisible under jeans, so you'll quickly forget that you're
wearing period panties. Please note, however, that the more absorbent the model, the thicker it is.

Learn more about our absorbent technology to better understand how our different fabric thicknesses work.

All our underwear can be worn for up to 12 hours depending on your flow. They absorb up to the equivalent of 4 tampons for our most absorbent models (our shorties or our cyclist).

The Choupette tanga is for light flows, the Félicie and Philomène panties for medium flows, the Armande shorty and the Simone panties are more suitable for heavy flows and/or at night, while our Louison cyclist is specially designed for hemorrhagic flows such as post partum or flows related to the wearing of a copper IUD for example.

Our eucalyptus fiber absorbent zone has anti-bacterial and anti-moisture properties: you stay dry and bacteria don't have time to grow. No risk of toxic shock syndrome with our lingerie. Our Elia lingerie is therefore not only hygienic, but also one of the best solutions for your body.

With our eucalyptus fiber absorbent zone, there are no bad odors: it has anti-bacterial properties and provides a fresh feeling to neutralize odors.

However, we recommend that you rinse it in cold water after wearing it, and put it in the machine quickly: any garment that stays wet for too long can develop a damp smell.

If an odor persists, you can always use a few drops of essential oils when putting it in the machine, but if you follow our care instructions, this should not be necessary.

Our menstrual panties are made to be worn up to 12 hours (different models depending on your flow). If you choose the good
model, there is no risk of leakage thanks to our absorbent zone doubled with a waterproof surface.

However, if your flow is very important or if you are afraid of leaks, you can also use conventional sanitary protection, but this is not compulsory.

The ideal is to see for yourself and to test our menstrual lingerie quietly at home on a heavy period day.

Our cotton is certainly organic as indicated on our site, but not only! Our menstrual lingerie is moreover labeled Origine France Garantie and Oeko-Tex, to cumulate all the advantages of each one and thus to remain in line with our values:

The Oeko-Tex label is not a guarantee of bio but of harmlessness of the product towards the body, thanks to a guarantee that the solvents used for the treatment of our materials are not harmful for the man. This certification is not an indicator of the organic or natural character of the
fiber (our PUL is a synthetic material, but it is well labeled Oeko-Tex).

The organic label, on the other hand, offers us a certain guarantee with regard to the environmental impact of the cultivation of our organic cotton, which limits the use of chemicals and whose absence already preserves the health of all the men and women who work in the harvest.

Finally, the OFG label, Origine France Garantie, is a guarantee of our desire to work locally as soon as possible, with the overwhelming majority of our manufacturing operations being carried out in our French workshop (design & pattern making, weaving and dyeing of cotton, assembly, sewing, packaging...).

Some women have a very central flow, which accumulates in the center of the panty, the narrowest area, causing it to overflow quickly, while
the rest of the absorbent zone is far from being saturated. Those whose flow direction is forward or backward generally benefit from a longer wearing time before the saturation of the absorbent zone!

This is by no means inevitable, as it is possible to use interlabial petals to redirect the flow and thus have a better distribution of bleeding.

Our products

We offer two product lines: adult and teen. We have established a size guide on each article page. We invite you to go to each product page, and click on "Choose my size", just under the sentence "add to cart".

Please note that each product size is different, so we advise you to check each item sheet before validating your cart.

Moreover, with the different washes, it is possible that our lingerie relaxes slightly, so if your panties, at reception, are slightly tight, don't panic, with the washes, it will be fine.

It is important, in order not to make mistakes, to take your measurements in the right place.

The exact place to take your measurements is at the level of the pelvis, at the widest point of the pelvis, but without the "saddlebags" which are normally found a little lower.

This can happen, we are sorry. Don't worry, it never lasts too long.

If the out-of-stock condition concerns one of our permanent models (Choupette, Philomène, Félicie, Armande, Simone or Louison), we invite you to subscribe to the alerts directly on our eshop. Usually, a few days later, you will receive a notification that the product is back in stock.

If the shortage concerns a limited edition, unfortunately, it will not be available anymore. Indeed, in order to limit waste, we do
what is called upcycling: we use pretty cotton scraps to create small limited editions, which go to
usually very quickly, so we invite you not to delay if you have fallen on the color.

Our menstrual panties are sold exclusively on our website. Do not hesitate to contact our customer service to be advised on the choice of the model or the size.

Our prices

At Elia, we have chosen to opt for a 100% French manufacture, with a valorization of all the links of the chain of
production: from the cotton manufacturer, to the seamstress who will make your panties, or the order preparer.

Sales and fast-fashion are often the result of an overproduction of textile products, at the cost of a disastrous ecological footprint and a waste of polluting raw materials during the manufacturing process. So at Elia, we prefer to produce exactly what we need, with natural and high quality raw materials. Our pricing policy is to offer you the best quality at the right price. We have chosen to produce everything in France to ensure traceability and maximum comfort of our panties, without compromise.

Within the framework of our sponsorship and loyalty program, you can however quickly benefit from advantages which enable you to acquire our pretty lingerie at a lower price.

Absolutely! If you're using disposable pads, that's a lot of money and waste that goes into the garbage every cycle. In the long run, period panties are more economical. But beyond the cost savings you make with
menstrual lingerie, using period panties is above all a commitment for the planet (zero waste, less pollutants...) and for the body
(100% organic cotton, no risk of toxic shock syndrome...).

Duration and maintenance

All our models can be worn up to 12 hours depending on your flow (we do not recommend wearing your lingerie for more than 12 hours for hygiene reasons, as for classic lingerie)

The Choupette thong is for light flows, the Félicie and Philomène panties for medium flows, the Armande shorty and the Simone panties are
more adapted for heavy flows and/or at night, while our Louison cyclist is specially designed for hemorrhagic flows such as post partum or flows linked to the wearing of a copper IUD for example.

You can also wear our lingerie in addition to classic sanitary protection if you are afraid of leaks.

Initially designed to be worn during your period, Elia lingerie is also very suitable for the following times:
- During your period, day and night
- With or without additional sanitary protection
- Before your period, if you are not sure when it will arrive and to be equipped in case of bad surprise
- When practicing a sport
- For light bladder leakage
- For white discharge
- After your childbirth once you are back home for post-partum bleeding, and to avoid the risks of irritation due to traditional protection
- During your pregnancy, for the small inconveniences that it can cause, in particular in the last trimester

And of course, as classic lingerie at any time of the month.

If you take care of it, our Elia menstrual lingerie has the same life span as a classic lingerie: 5 to 7 years!

To know more about the care, go here.

In order to keep your lingerie as long as possible, we advise you to follow our care instructions:

- Rinse your underwear in cold water until the water is clear, as soon as you have finished wearing it
- Wring it out gently, without wringing it out, before putting it in the machine as soon as possible
- Machine wash: at a low temperature (40°C maximum), with a glycerine-free detergent (avoid fabric softeners and other softeners, which are often very "greasy", and opt instead for white vinegar to soften your laundry)
- Air dry

For more information and advice on how to care for your Elia menstrual underwear, visit this page.

Hand washing is possible of course, but we prefer to advise it in an exceptional way. Indeed, a hand wash is
finally more aggressive for the fabrics than a machine wash (we rub more, we wring out by twisting the panties in all directions, etc...)
which in the long run, damages and relaxes your lingerie, Elia or other.

We prefer to recommend a hand wash during the cycle if you wish, and a machine wash, all the same, at the end of each

You can find our care tips right here.

It can happen: it is indeed a phenomenon of discoloration that can happen when some of us have vaginal secretions
a little more acid. This just discolors the cotton but does not affect the proper functioning of the panties.

To minimize this, rinse them in cold water without soap as soon as possible after wearing them! And then put them in the washing machine, but otherwise it's just a cosmetic issue!

It is a problem that is specific to all black bottomed panties (menstrual or not) because it depends on our personal acidity (white discharge like blood), which can vary and be more or less important during the same cycle.

A lighter colored absorbent pad would leave traces of blood after washing, which is why we chose the black color.

This does not spare organic cottons and Oeko-tex certified fabrics and is in no way a sign of poor quality materials. Once again, there is no need to worry, it does not hinder the effectiveness of our products!

We generally advise in these cases to change your clothes more regularly and to rinse your underwear quickly after wearing it if you do not want to alter the aesthetics of your panties.

We strongly advise you to use a hypoallergenic and glycerin-free detergent for Elia lingerie, and in general for all clothes worn close to the body. We also offer a menstrual detergent dedicated to the care of
period panties.

To soften your clothes, do not use fabric softener: if your water is hard and chalky, prefer white vinegar which has anti-chalk properties and helps to fight against the dryness of clothes after washing. It also neutralizes bad odors. You will avoid using chemical and perfumed products from the market, which are not recommended for underwear worn close to the body anyway!

Glycerine will eventually clog the absorbent fibers and make them waterproof in the long run: liquids may bead up on the surface, which is less effective!

For example, be careful with the composition of Marseille Soap: only a tiny amount of glycerin from the natural saponification process should remain in the original recipe.

For the same reasons, we do not recommend the use of fabric softener because these are greasy compositions formulated to limit static electricity and soften the linen but which reduce the efficiency of absorption and clog the machines in the long run! Moreover, you should not use them on all absorbent household linen: bath towels, dish towels... as well as sportswear and menstrual panties!

If your lingerie has been washed at more than 40° or has been accidentally put in the dryer, no need to worry!

However, we recommend washing at a low temperature for the following reasons:

The absorbent zone made of eucalyptus fibers tends to shrink slightly under the effect of heat. It's still as absorbent as ever, but you may notice that the cotton on top, which hasn't moved, wrinkles under the effect of the slightly shrunken absorbent layer. It's just less aesthetic!

Blood "cooks" at high temperatures, so stains are harder to get out once they've been heated: that's why it's best to do a manual rinse with cold water first. However, the inside of our panties is all in black, to avoid unsightly stains.

The life span of your panties (and that of classic lingerie) is reduced with high temperature washing, so it is better to avoid it!

Environment and eco-responsibility

We try to choose our fabrics in an environmentally friendly way. To learn more about the different materials that make up our lingerie and the absorbent zone, discover our technology in more detail. To learn more about our eco-responsible actions, click here.

At Elia, we don't use any material made from animal fibers: our absorbent zone is made of wood fiber textile and the fabric of our panties is made of cotton. Our menstrual stain remover is also vegan, and made entirely without beef gall.

Absolutely, all our panties are Oeko-tex certified and our cotton is certified organic, to guarantee your well-being.

To learn more about our certifications, take a look here.

Our Elia lingerie is made in our workshops in France, from design to delivery, including cotton weaving. Whenever possible, we favor short circuits for our supplies and our partners.

All our lingerie models are made of our organic cotton (to which we add between 3% and 5% of elastane for more comfort and flexibility), an absorbent fabric made of eucalyptus fibers (eucalyptus tencel) and a waterproof fabric made of breathable PUL.

France is just starting to produce organic cotton and we are trying to source in the future on our local market, but today the volumes are insufficient and the world production of organic cotton is more assured by the United States, India and Egypt but this list is not exhaustive (Turkey and China can also come to complete the list). The supply of our partners for the raw cotton yarn is therefore variable throughout the year depending on the harvest.

Our organic cotton is then entirely woven in our workshop in France, our waterproof fabric comes from European suppliers, while our absorbent fabric is from an Austrian production.
