Size Chart
Frequently Asked Questions
What is my size?
We recommend consulting our size chart and fit quiz. These will help you find the right size. You can find them on every product page below the sizes. Not sure between two sizes? Go for the smaller size. Our swimwear is made from a comfortable and stretchy fabric that adapts to different body types. Check the size chart or take our fit quiz.
Does the fabric become see-through when wet?
No. Our swimwear is made from high-quality fabrics and consists of two layers of fabric, as each item is reversible. This double layer provides extra coverage, making the swimwear feel comfortable and confident both dry and wet.
Can I return my order?
Yes. You can return your order if it does not fully meet your expectations. For hygiene reasons, we only accept returns when: the item is unworn and unwashed, the hygiene strip is still in place, all labels are still attached, and the item shows no make-up stains, odours, or other signs of use. You can easily register your return via our returns page.
How do the Billie styles with a swimsuit look work?
Some Billie styles are designed with the appearance of a swimsuit, but the ease and flexibility of a bikini. These sets consist of a top and bottom that together create the look of a swimsuit, while you enjoy all the benefits of a bikini. This way you can more easily choose the right size for both the top and the bottom, enjoy extra comfort during a beach day, and make bathroom visits much easier. Many women choose these styles because they combine the elegant look of a swimsuit with the wearing comfort of a bikini.
Are the cups removable?
Yes. Our tops come with removable cups, which can easily be removed or reinserted through the subtle side openings. This way you can decide for yourself how much shape and support you prefer. Do you prefer a more natural look? Then you can simply remove the cups.
Is Billie swimwear reversible?
Yes. Our swimwear is designed to be worn on both sides. This way you enjoy two looks in one item. Because each item consists of two full layers of fabric, you benefit not only from two different looks, but also from extra comfort and coverage. Perfect for those who like to switch things up without bringing extra items on holiday.
