1920s Flapper Silhouette

The flapper silhouette dropped the waistline seam from its natural position all the way to the hip, flattened the bust rather than emphasizing it, and let hemlines rise - first to mid-calf, eventually to the knee by the second half of the decade. After a century of corsetry building the female silhouette outward and inward at the waist, this was a genuinely radical shift in the other direction: straight up and down, unstructured, made for movement.

What strikes me most sewing reproductions of this era is how much of the visual interest moved off the seams and onto the surface - beading, fringe, elaborate embroidery - precisely because the cut underneath was so simple. A 1920s dress is often just a couple of straight or slightly A-line panels; the drama is all in what's layered on top and how it catches the light in motion.

It's also, not coincidentally, the era where the underlying support garments changed character entirely - corsets gave way to bandeau-style bust flatteners, which shows up directly in how the outer garments could be cut.
