Inspired by “secretaries throughout time in films,” the designer staged a spirited musical with dancers as her models.

Birding-meets-“Troop Beverly Hills” was the inspiration for Rachel Antonoff's lineup, with camp uniform looks and playful prints.

The lineup — which was perfectly cute — included men’s tuxedo and pajama shirting, plaid pleated skirts, powder-blue denim overalls and collegiate sweaters.

The designer went adorably preppy with seersucker dresses, fit-and-flare numbers and shirtdresses with printed panel inserts.

Despite a significantly shorter do, “Girls” star Lena Dunham was instantly recognizable at Saturday’s presentation.

The designer went back to her childhood and a game she used to play, pretending her bed was a raft drifting through a magical lake.

The girls were as sweet as can be with trombone-print dresses, bow blouses with pleated skirts and plaid frocks.

The nostalgia-infused lineup offered plenty for the young and hip, as well as a few more polished pieces for a slightly older demographic.
