Support Built for A-C Busts
The Rhythm Classic Underwire Top is built to offer more support, lift, and shape for A-C busts, making it a go-to for anyone searching for a real underwire bikini top rather than a soft cup style.
What Gives It That Support
Crafted from ECONYL recycled fabric, the main body is 78% recycled nylon and 22% elastane, with a lining of 91% recycled nylon and 9% elastane. A tailored metal underwire delivers high level support, and adjustable shoulder straps with a back clasp let you dial in the fit. The hardware is chlorine and saltwater safe zinc alloy, so it can handle both pool and ocean days.

Who It Is For
This top is for anyone with an A-C bust who wants real underwire support in a bikini top rather than a soft, unstructured cup, whether that is for a day at the beach, a pool day, or a boat trip along the coast.
Wearing and Caring for It
Because the hardware is built to be chlorine and saltwater safe, this top can go straight from pool to ocean without issue, but like any swimwear it lasts longest when rinsed in fresh water after each wear and air dried rather than machine dried, which helps protect both the elastane stretch and the underwire shape.
The Rhythm Story
Rhythm brings together a unique group of individuals with a shared livelihood doing what they love, and the Classic Underwire Top reflects that same attention to real function, using ECONYL and durable, saltwater ready hardware.
