Her smile.... was fashioned with wide, full lips exquisitely accented in a shade of shocking pink which matches the hue of her Adrian suit.... sleek squarey shoulders, and topped by an attractive but unnecessary scrap of hat.
When I first read this is the story “Luella” about a very bad woman in a story in Saint Errant by Leslie Charteris from 1948, I thought, hmmmm, square shoulders, silly hat, yes, but Adrian suit in shocking pink?
Most of the suits I have seen by Gilbert Adrian, who made clothing for Hollywood films and for his own line, were more sober than that. But I poked around the online Costume Collection at the Metropolitan Museum of Art and found he did indeed do some bright suits in the 1940s. They have an orange suit and a truly wacky suit with the jacket in half pink and half gray with mirrored appliques worn with a purple skirt. Not many women would have opted for such a memorable item as they expected to wear their suits every week regularly for 2 or 3 years. Blacks, blues, browns, and beiges would be more popular. Not that Adrian settled for the plain blazers we sport. He loved to play with stripes and loved self-trim appliques.
