Retro details. Modern support.
This top brings major vintage energy with black-and-white contrast trim, a sleek center ring, and two signature buttons where the shoulder straps meet the cups. It’s designed to flatter with just enough structure, featuring:
- Elastic-lined shoulder straps wrapped in soft recycled fabric
- Zigzag stitching for a nostalgic edge and gentle support
- Adjustable tie-back for a custom fit on every body
- Fully lined with a soft, lightweight interior
Wear it your way—whether you’re lounging poolside or making moves in the sun.
Fit Notes – Siena’s Button Bikini Top
-
Xufe is 5'7" and wears an XS top
– The elastic straps and adjustable tie-back give her a snug, supportive fit without any digging. The buttons sit just right over the bust. -
Storrey is 5'6" and wears an XXL top
– The top offers great coverage and support with room to adjust. The shoulder straps stay secure without slipping, and the tie-back allows for easy adjustment.
Fit tip: If you're between sizes, we recommend sizing down for a snugger fit—the elastic and tie-back will flex with you.
