Jason Wu Pre-Fall 2013 | Pictures

A day before he presented his Pre-Fall 2013 collection to editors and buyers, Jason Wu posted a photo of "Martha Hunt giving Jerry Hall realness" to Instagram. If Hunt was busy channeling that queen of '70s glamour and seduction during the lookbook shoot for this offering, it's because that's the feeling Wu was after.

Extending the unexpectedly sexy tone of his Spring 2013 collection, Wu created a luxuriously worked collection of dresses and gowns that captured the liberated spirit of the decade. The sheer chevron panels on his evening gowns, for example, alternated with wide swaths of sequins that kept the wearer covered up. Elsewhere the sex appeal toughed up, with dresses and slim trousers in leather (or a graphic black, white, and yellow eel skin pattern) and belts accented by chain-link hardware.
