Sweeps diagonally over one shoulder and leaves the other bare.

The basics
What to know about one-shoulder
A one-shoulder neckline draws a single diagonal from beneath one arm up and over the opposite shoulder, leaving the second shoulder fully bare. The lineage is classical; the line reads as a modern cut of the single-shoulder draped garments of ancient Greece. This is part of why it photographs like statuary.
Asymmetry is the entire statement. One diagonal breaks the symmetry every other neckline preserves. The eye travels the line, and the look reads deliberate and evening even in plain fabric. Stylists reach for it when a dress must carry a room without ornament. The covered side often extends into a single sleeve, which adds drama and, in cold rooms, function to exactly half of you.
Support and styling both narrow. The bodice hangs from one shoulder, so structured versions add an internal band or boning at the ribcage to stop rotation. That rotation is the slow spin a loose one-shoulder dress performs through an evening. A strapless bra or built-in cups handle the bare side. Necklaces fight the diagonal, so jewelry moves to the ears and the bare arm, a cuff or bracelet on the exposed side balancing the covered one. Inspect the underarm fit on the open side, since gaping there shows everything a mirror will not.
