x REVOLVE Layana Bottom

This bikini bottom features a high-cut leg and a narrow, minimal-coverage silhouette that sits high on the hip. The cedar brown fabric is embedded with metallic fibers, creating a distinct, light-catching shimmer that leans into Costello’s penchant for high-octane glamour. It is a sharp, intentional piece of swimwear designed for maximum exposure and a sculpted line.

Safety Rating: Lowest

Analysis: The garment is constructed from a blend of nylon, elastane, and metallic fibers, all of which are petroleum-derived synthetics. These materials lack breathability and pose a risk for microplastic shedding and chemical transfer when exposed to moisture and heat.
