Size guide
We know that shopping online for swimwear can be tricky since you can't try it on. That's why we created this guide so you can be sure of picking the right size. Petit Bain swimsuits and bikinis are currently available in three sizes (I, II, III) created to fit most body shapes and sizes.
These sizes do not correspond directly to other sizes so you can see the size chart below as a guideline.
Take your measurements with the images below as a guide to find the size that suits you best. Remember to keep you back straight and a relaxed pose to get the most accurate measurements.
You can also use another bikini that fits you well and measure the corresponding sides to compare. During manufacturing we have an error range of 0,5cms so feel free to measure to the cm.
New swimsuits usually fit tight because elastic bands are new, with time they will adapt to your body and feel completely comfortable.

Finally, remember:
New swimsuits are usually tight because the elastics are unused. With time and use, the swimsuit will adapt to your body and will be more comfortable to wear.
