Why You'll Love It
Not quite a cover-up, not quite a dress — the Sinner Dress is for when you’re slipping from sea to dance floor, still wet from the pool, and ready for trouble. Made from our signature luxe sheer fabric, it’s feather-light, ultra-soft, and unapologetically sexy. Wear it barefoot at golden hour, layered with nothing, or tossed over your tiniest bikini at a DJ set in Ibiza. You don’t need much — just this. • Available in limited colors per drop • Handmade in LA in small batches • Stretchy, breathable, and barely-there feel Color way Tangie is sewed with Aqua contrast thread.

Meet Amanda, Our Founder
“I launched Banshee Swim to disrupt the industry with pieces that are unapologetically bold, ethically made, and built to last. Sustainability isn’t a trend—it’s the baseline.”
Owner and designer Amanda Fronckowiak created Banshee after becoming disillusioned with the mundane 9-5, and pivoted to bring her vision of unique yet sustainable swimwear to the Banshees.
Designed in LA and made for the loud ones, Banshee Swim offers swimwear for the brave and the bold.
