Giulietta designer Sofia Sizzi has a straight-up obsession with sixties-era cinema, which in a way helps explain the extreme focus of her collections. "I always go back to some vintage reference point," she said at her Soho showroom. For Resort it was 1969's La Piscine, starring Romy Schneider (who was also name checked by Scott Sternberg at Monday's Band of Outsiders presentation). "It was super-glamorous, the effortless way she's just walking around this one house," said Sizzi. "It's a beautiful way of dressing up."

To convey that idea of relaxed glamour, the designer styled a sizzling halter-neck jumpsuit—the top resembling a vintage maillot—with a pair of casual-but-pristine white sneakers. A white and burgundy pleated skirt, inspired by a tennis uniform, was worn with a dressy, strong-shouldered blazer. And a white minidress, with a sliver of a keyhole neckline, was layered over a long-sleeve white tee.

So yes, there was a lot of white, including Sizzi's other jumpsuit, which was worn by Jessica Stam to Monday night's CFDA Awards. With it, the designer managed to update the peplum, letting it lie flat against the body. Much like its inspiration, Schneider, the piece was an utter knockout.
