The Must-have One Piece Swimsuit for EVERY Woman

Today's one-piece swimsuits go far beyond the basics — offering tummy control, bust support, sustainable fabrics, and runway-worthy details like corset tie-backs, plunging V-necks, and metallic Lurex blends. Whether you want sleek and minimal or bold and fashion-forward, there's a cut designed for your body and your style.

When choosing yours, focus on three things: a cut that complements your shape, a fabric suited to your activity (chlorine-resistant for laps, textured blends for resort wear), and support features — underwire, removable cups, or compression panels — that make you feel as good as you look.

FAQs

Are one-piece bathing suits more flattering?

For most body types, yes. One-pieces create a continuous, unbroken line from chest to hip, which naturally smooths and elongates the silhouette in a way a two-piece can't. Styles with ruching, a V-neckline, or a wrap front add extra shaping — but even a simple one-piece tends to be more forgiving and polished than a bikini.

Is a tankini a one-piece?

No. A tankini is technically a two-piece — a longer tank-style top paired with separate bikini bottoms. It offers more coverage than a traditional bikini but doesn't have the built-in structure, compression, or continuous shaping of a true one-piece swimsuit.

Should I size up or down in a one-piece swimsuit?

Neither automatically. Start with your current bust, waist and hip measurements. If those measurements fit but the suit still pulls vertically, check whether you need a long-torso style rather than simply going up a size.
