Sack dress silhouette

A dress silhouette with loose straight hang and no waist definition—the 1950s–1960s sack form on simple day dress, distinct from shift as general straight hang and from tent shoulder-volume A-line.

How to recognize it

Sack dress silhouette shows loose straight body with no waist seam or shaping from shoulder to hem.

Shift silhouette is the broader straight-hang cousin. Tent silhouette adds shoulder volume and A-line flare.
