I had no idea I needed pockets in a swimsuit until I got this one from up&downn. Seriously, it’s a game-changer! I can keep my phone or keys with me and not worry about leaving them behind. Plus, the suit fits so well—super flattering and comfy. It’s officially my new favorite for beach days!
Alice –
Absolutely love this swimwear! It fits me so beautifully and the design is flattering. The material is nice and thick which gives them a luxe and quality feel.
