Measured: Judged in profile: where the dress holds close, where the line releases, and whether the outline follows the body without horizontal pulling.
The basics
What to know about dress silhouette
Silhouette, the line a dress draws from shoulder to hem, decides more of the buying choice than any other single detail. It sets where the fabric holds close, where it releases, and how much the fit can forgive. The shape also sets what the dress reads as before anyone notices the color. Two dresses in the same size and fabric behave completely differently when one grips the hip and the other skims past it.
Dressmakers judge silhouette in profile, not head on. Stand side-on to a mirror at arm's length and trace the outline. A fitted line should follow you without pulling. The flared line should break cleanly from its release point at the waist or shoulder. Any silhouette that wrinkles horizontally is too tight at that spot, and one that collapses vertically carries too much cloth.
Read the six options as a scale of shaping. A sheath commits to the body along its whole length, and a shift refuses the waist entirely. The rest sit between: A-line and fit and flare release at the waist by different amounts, and a wrap makes the waist adjustable. A gown is any of these carried to the floor in occasion fabric. Pick the release point first, then the length.
