1950s Hourglass Silhouette
The nipped waist and full skirt of Dior's New Look carried through most of the decade, giving way by the late 1950s to Balenciaga's looser sheath and chemise shapes.

Dior's 1947 New Look didn't stay a single season's controversy - it set the template most of the 1950s built on: a fitted, often boned bodice cinched at a natural waist, over a skirt full enough to need serious support underneath, usually multiple layers of stiff tulle or a structured underskirt. As the decade went on, other houses pushed variations without abandoning the waist-defined premise - Balenciaga and Givenchy introduced straighter suits and sheath dresses that skimmed rather than exaggerated the figure, still clearly fitted but less architected than the New Look proper. That loosening became explicit in 1957, when Balenciaga showed the chemise dress - a straight, waist-skimming shape that dropped the cinched waist almost entirely and pointed straight at the next decade.
Building this silhouette is really two separate construction problems stacked on top of each other: a fitted, often boned bodice doing close work at the waist and bust, and a full skirt doing volume work below it, with the waist seam as the only place they have to agree. I lean on boning for the bodice on any serious reproduction - a fitted 1950s bodice without at least some internal structure won't hold its line through a night of dancing - and multiple layers of gathered or pleated tulle for the underskirt rather than trying to get volume from the fashion fabric alone, which usually just looks heavy instead of full.
The chemise dress at the very end of the decade is worth sewing once just to feel how different "loose but fitted" is from "fitted then flared" - it's a genuinely different set of decisions about ease and drape, and it's the shape that the following decade runs with almost immediately.
