Cosima Top

This white swim top leans into the structural language of lingerie, featuring underwire cups and a delicate lace trim that traces the neckline. The nylon-elastane blend provides a firm, smoothed fit, while the adjustable straps and S-hook closure allow for a custom tension across the back. It’s a study in sultry minimalism, trading typical athletic swimwear construction for an after-dark, boudoir-inspired silhouette.

Safety Rating: Lowest

Analysis: Composed of 82% nylon and 18% elastane, this piece is entirely petroleum-based synthetic. These materials lack natural breathability, carry a high risk of microplastic shedding, and are prone to trapping heat and moisture against the skin.
