Frequently Asked Questions

Sienna Swim was founded by designer and owner Sienna Mae Gomez, whose passion for swimwear and honoring femininity in every form come together in her line!

For your convenience, we have listed all model measurements and sizes in the description of our suits for reference. Before you buy, we suggest reviewing our size chart and taking your measurements to ensure the best fit!

All of our collections are limited release, meaning you’ve got to get them while they’re here! We may bring back your favorite styles, though, so make sure you’re signed up for our mailing list so you can be the first to know when new designs are dropping! We’ll also announce new drops via Instagram @SiennaSwim.

Sienna Swimwear uses the highest quality fabrics, which means you’ll have to take some extra care in wearing and washing your pieces. We recommend handwashing with a mild detergent in cold water and hang drying in the shade. In order to prevent pulling of fabric, please avoid contact with rough surfaces. To extend the life of your pieces, we recommend rinsing immediately after use, especially after using sunscreen and oils, as they can stain or damage the fabric.
