Chapter 2 traced the political and economic forces that made women's trousers possible. This chapter follows the parallel story of how trousers became fashionable — glamorous, even — largely through the influence of a handful of designers and performers who understood that a trouser on a woman's body could be its own kind of statement.

Marlene Dietrich and the Tuxedo Provocation

In the 1930 film Morocco, Marlene Dietrich appeared in a full white tie and tuxedo, complete with top hat, and kissed another woman on screen — a moment that remains one of the most quoted images in early trouser history. Dietrich continued wearing tailored men's-style suits off-screen through the 1930s, in an era when doing so was genuinely unusual for a public figure and drew heavy press commentary. As Chapter 2 notes, some of the specific anecdotes attached to her trouser-wearing — including a widely repeated claim that she was arrested in Paris for it — do not hold up against the contemporary press record and should be treated as fashion legend rather than documented fact. What is well documented is simply that she wore them, consistently and publicly, at a time when that alone was a statement.

Dietrich's look was not utilitarian, unlike wartime coveralls — it was deliberately, theatrically glamorous. She proved that a trouser suit could be as seductive and image-defining as a gown, decoupling trousers from purely practical justification for the first time in mainstream popular culture.

Coco Chanel: Ease as Luxury

Coco Chanel approached trousers from a different angle: comfort as a form of luxury. Chanel herself was photographed in wide-legged sailor-style trousers on the French Riviera in the 1920s, and she designed trousers and trouser-adjacent beach pajamas for her wealthy clientele's leisure wear. Chanel's broader philosophy — that restrictive, decorative dress was a form of oppression, and that ease of movement was itself elegant — laid essential groundwork for trousers to be understood as chic rather than merely permissible.

Katharine Hepburn and Hollywood Off-Screen Style

Where Dietrich played with androgyny as spectacle, Katharine Hepburn wore tailored trousers as her genuine, consistent personal style, both on-screen and off. Hepburn favored simple, well-cut trousers, often paired with button-down shirts, at a time when studios pressured female stars to appear exclusively in skirts and gowns for publicity. Her persistence — reportedly including refusing to change out of trousers when studio staff hid her clothes — helped normalize the tailored trouser as everyday wear for women who could afford to defy convention.

Postwar Contraction and the New Look

It is worth noting that trouser progress was not linear. Christian Dior's 1947 "New Look" — with its cinched waists, padded hips, and voluminous skirts — represented a conscious return to hyper-feminine, trouser-free silhouettes after the wartime years of utilitarian dress. The New Look dominated mainstream women's fashion through much of the 1950s, illustrating how postwar culture often pushed women's fashion backward toward restriction even as the underlying social and economic case for practical dress remained.

Yves Saint Laurent's "Le Smoking"

The decisive turning point came in 1966, when Yves Saint Laurent introduced "Le Smoking" — a woman's tuxedo suit, tailored with the same precision and formality as menswear, worn without apology as evening wear. Unlike earlier trouser moments, which were often framed as either purely functional or as calculated transgression, Le Smoking was presented as couture — high fashion in its own right, deserving of the same reverence as a gown.

Design Milestone: Helmut Newton's 1975 photograph of a model in Le Smoking, cast in the sharp shadows of a Paris street at night, became one of the most reproduced fashion images of the 20th century, cementing the tailored women's trouser suit as a symbol of confident, assertive sensuality rather than its opposite.

Le Smoking mattered because of what it implied structurally: that women did not need to borrow the silhouette of femininity from skirts and gowns in order to be perceived as feminine, confident, or desirable. The suit itself could carry that meaning.

The 1970s and 80s: Power Dressing Emerges

Following Saint Laurent, the 1970s and 1980s saw trouser suits move decisively into mainstream professional dress, as growing numbers of women entered corporate and political workplaces. Designers including Giorgio Armani built entire reputations on softly tailored trouser suits for working women, moving away from rigid, masculine-mimicking cuts toward silhouettes engineered specifically for the female form — a shift explored further in Chapter 31 on the power suit trouser.

By the close of the 20th century, the trajectory begun by Dietrich's provocation and completed by Saint Laurent's couture legitimization had fully arrived: the trouser suit was no longer a statement of defiance. It had simply become one of the primary vocabularies of women's fashion, available to be worn as casually or as formally as any skirt or dress.
