What Is a Dress With One Strap Called?

A dress with only one shoulder strap is called a one-shoulder dress , an asymmetrical style that leaves the opposite shoulder bare. You may also see “single-strap dress,” but “one-shoulder” is the clearest term to use when you’re browsing styles or describing the neckline you want.

Unlike a strapless dress, a one-shoulder dress has fabric or a strap extending over one shoulder; unlike a halter dress, it does not rely on a neckline that wraps around your neck. The shoulder detail can be narrow or wide, so the name describes the asymmetrical placement rather than one specific strap shape.

When you try one on, raise your arms and sit down to see whether the neckline stays where you want it and whether the strap presses into your shoulder. A comfortable fit should feel secure through the bust without requiring you to keep pulling the unsupported side up; consider a strapless or convertible bra if you want coverage without a visible second strap.

A one-shoulder neckline can make a simple dress feel distinctive for a party or summer outing, while the dress’s length, fabric, and styling determine how casual or dressy the overall look feels.
