Tonie Bikini Bottom

This bikini bottom features a high-cut leg and slim, adjustable side ties that prioritize minimal tan lines. The honeycomb polka-dot print against a saturated yellow ground offers a playful, retro-leaning aesthetic that leans into the brand’s focus on low-key, vacation-ready separates.

Safety Rating: Lowest

Analysis: The composition is a blend of polyester and elastane, both of which are petroleum-based synthetic polymers. These materials offer low breathability and carry a risk of microplastic shedding and potential chemical transfer to the skin during perspiration.
