Ruched Halter One-Piece Swimsuit with Open Back

Ruched Halter One-Piece Swimsuit by Sidway Swim

Meet your new favorite getaway essential: a sleek one-piece that combines a softly twisted halter neckline with elegant all-over ruching and a beautifully open back. Selected for the Sidway Swim collection, this women's one-piece swimsuit is designed to create an eye-catching, refined silhouette for poolside afternoons, seaside escapes, and sun-filled vacations.

Design Highlights

• Twist-front halter neckline: a flattering V-shaped front with softly gathered detail creates a polished, feminine finish.
• Ruched waist and torso: carefully placed gathers add texture and shape without requiring a bold print.
• Open-back design: a halter tie at the neck and a low-cut back give this one-piece an airy, statement-making profile.
• Side cutout detailing: discreet open sides add a modern twist to a timeless silhouette.
• Soft, stretch swim fabric: polyamide and elastane blend intended for easy movement and swim-ready styling.
• Comfortable padded cups: includes padding without underwire, as stated in the supplier's product specifications.
