First Light Sunflash Bikini Bottom

Shirred elastic creates a puckered, tactile texture across this low-rise bikini bottom, which blends an electric blue into bubblegum pink. Slim, pale yellow string ties sit high on the hips, giving the minimal coverage cut an adjustable fit that resists digging in. The dense micro-smocking keeps the lightweight stretch knit anchored without relying on heavy binding.

Safety Rating: Lowest: Petroleum/Plastic-Based Synthetics

Analysis: Constructed entirely from a high-spandex polyester knit, this piece relies on non-biodegradable petroleum synthetics that offer minimal breathability against the skin. These synthetic microfibers carry a higher potential for chemical leaching and microplastic shedding, particularly in wet, chlorinated, or saline environments.
