Our Arielle swimsuit bottoms are lightly sheathing and have a snug fit. This model is cut just above the thighs to prevent flow when getting out of the bath. We recommend going up a size if you have bouncy thighs or buttocks. If you already have our Simone model, the fit of this model is similar.
Measure directly on the body, without tightening. Hip circumference is the widest point below the waist (usually at buttock level). Please note that our models relax slightly with washing.
If you're still in doubt about which size to choose, take your favorite panty and measure the width at the waist from edge to edge. Please note that not all models can be worn in exactly the same way and do not have the same elasticity, so measure with a model similar to the one you want (take a high-waisted model to choose your swimsuit size, a shorty or boxer for Armande, etc.).
