A dress that has no shoulder straps, attached sleeves, halterneck or other shoulder- or collarbone-related attire holding up the upper portion of the dress, instead relying on the tightness of the dress (usually around the hip or waist area) to keep it in place. The shoulders and upper chest area should be bare, which also implies the lack of a strapped bra.
Strapless dresses must not cover the shoulders or arms in any way outside of separate articles of clothing or jewelry such as detached sleeves, gloves, or armlets.
