Gia Top (Black)

Not sure about your size? No worries. If your bikini doesn't fit the way you want, we'll cover the shipping for your first exchange. Your perfect fit is on us. Just email us at info@tranquilaswimwear.com to get started. *Applies only for orders in U.S and Canada.

Our swimwear blends timeless design with eco-conscious innovation. Each piece is crafted from Amni Soul Eco®—the world's first biodegradable nylon—offering exceptional comfort, four-way stretch, and UV protection (UPF 50+).

Lightweight, breathable, and quick-drying, this high-performance fabric is made to withstand sun, salt, and surf while maintaining its shape and softness season after season. Unlike traditional nylon, Amni Soul Eco® breaks down in just ~5 years in landfill conditions, helping reduce long-term waste.

Every style is produced in small batches, with a focus on quality, fit, and sustainability so you can feel as good as you look.

Material: 90% Polyamide + 10% Elastane

Please follow these instructions to keep your swimsuit looking its best.

-Hand wash cold with a mild, bleach-free detergent and lay flat to dry in the shade. Wash immediately after use.

-Avoid hot water.

-Do not wring or twist the bikini—instead, gently press out excess water.

-Avoid contact with dark or heavily dyed items, and never wash with other garments to prevent color transfer.

-Let sunscreen, tanning oils, and lotions fully absorb into your skin before wearing, as they may cause staining or discoloration.
