Double-Strap One-Shoulder Cutout Swimsuit

A clean solid color makes the asymmetric silhouette the focus of this one-piece from SIDWAYSWIM. Two slim parallel straps sit over one shoulder, while the opposite shoulder stays open. Curved cutouts frame the waist and leave a narrow fabric connection through the middle, creating a distinctive shape from the front and back. The look is simple in color and expressive in its lines, with enough visual detail to style on its own for a poolside afternoon or a beach holiday.

Design details

• One-piece construction with an asymmetric, one-shoulder neckline and two narrow shoulder straps.
• Open waist sections on both sides create the cutout silhouette, with a fabric bridge joining the upper and lower portions.
• Solid-color finish keeps the neckline and waist shape clearly defined; the design does not rely on an all-over print.
• Padded bust construction without underwire. Brief-style lower coverage completes the swimsuit.

Color and fabric

White; Black. Nylon-based swim fabric. Choose White for a bright, minimal look or Black for a deeper, graphic finish. Each option uses the same asymmetric design.

Size and fit

Available in M, L, XL. These are the garment's labeled sizes; letter sizes can differ between brands. Compare your bust, waist, and hip measurements with the measurements for this style before ordering. For a one-piece, torso length also affects the fit. If you need help choosing, contact SIDWAYSWIM before placing your order.

Styling

Wear the swimsuit as the focal point with a loose shirt, a simple wrap, or relaxed beach trousers. A plain cover-up leaves the double straps and waist openings visible without competing with their shape. For a coordinated travel wardrobe, repeat the swimsuit color in your sandals or beach bag. Accessories and cover-ups are styled separately.

Care

Follow the sewn-in care label for the final washing instructions. As a gentle care routine, rinse in cool fresh water after wear and hand wash with a mild detergent suitable for swimwear. Avoid bleach, vigorous wringing, and prolonged soaking. Reshape gently and allow to dry in the shade, away from direct heat. Let the garment dry fully before storing, and take care around rough pool edges or abrasive surfaces.
