Side-Tie Bikini Bottoms with Adjustable, Flattering Swim Fits

Our side-tie bikini bottoms are made for merbabes who love an adjustable fit with a little extra personality. These bottoms feature tie-side details, ring accents, fringe, beads, pearls, and strappy silhouettes that let you customize how they sit on your hips — low and relaxed, higher and leg-lengthening, or somewhere perfectly in between.

This collection brings together side-tie bikini bottoms from across Salty Mermaid’s favorite swim drops, including bold solids, tropical prints, shimmer fabrics, runway-inspired details, and mix-and-match styles. From cheeky and semi-cheeky cuts to semi-Brazilian and Brazilian coverage, each bottom has its own shape and vibe while keeping that flirty, adjustable side-tie feel.

Whether you’re styling a classic triangle bikini, pairing a statement bottom with a matching swim top, or building a vacation-ready look with your favorite cover-up, our side-tie bikini bottoms are designed to move with you and flatter from every angle. Think flexible fit, bold details, and signature Salty Mermaid confidence in every tie.
