Square-Neck Swimsuits & Clean Lines

A square-neck one-piece sharpens the collar line and frames the décolletage. Each suit keeps the plane clean across the chest for a modern, camera-ready look. For a wider variety of cuts, explore our complete one-piece swimsuits collection.

Neckline & Support Options

Select slim straps for a minimal vibe or wider straps for enhanced support. Whether you prefer a high side seam or a smooth back finish, this silhouette balances structure with comfort.

Vacation Styling & Trends

This style pairs effortlessly with denim shorts or a sarong. Looking for the latest trends? Browse all new swimwear to find fresh color stories and prints for your next vacation.

Fabric & Finish

Matte fabrics maintain rich color depth in bright light, while subtle ribbing adds gentle texture without bulk—keeping the square-neck profile crisp from the pool to the patio.

What makes a square-neck one-piece look different from scoop or V necklines?

The squared frame visually straightens the collar line and broadens the shoulder plane slightly, giving a modern, architectural look that photographs cleanly from front and three-quarter angles.

How do I choose strap width for a square-neck swimsuit?

Slim straps keep the neckline minimal; wider straps add stability and can soften pressure on the shoulder. Pick by bust support needs and how much visual contrast you want at the shoulder.

Will a square-neckline stay flat when I move?

Look for a lined front panel, stable elastic along the neckline, and a firm under-bust. These details help the square edge sit flush while you swim or walk.

What jewelry suits a square-neck one-piece?

Try a short, fine chain or a small pendant that sits inside the frame; avoid long pieces that cross the edge. For metal tone, match suit hardware or your usual earrings.

Matte or ribbed for photos and bright sun?

Matte preserves even color on camera; subtle rib adds depth close-up without glare. Both finishes keep the square-neck profile crisp in direct light.
