Fashion has a constant case of nostalgia, and the newest-old-thing is the Baja.

This surfer staple (hello, Jeff Spiccoli!) is fast becoming the ne plus ultra of the too-cool-to-look-like-I-care crowd.

Throw one on over a gown (a la Celine resort) for the "Shaman Hippie Hollwood" look, as Phoebe Philo called it. Or, pair one with sporty printed short-shorts for an urban day vibe (thank you, Proenza, also Resort).

Fortunately, one need not go to Bergdorf's to shop for this beach wear staple (or wait until November). Cool young Brooklyn-based designers Ace & Jig developed their own line of Baja fabric in India, and offer the classic hoodie, and dresses too.

For the legit iteration, which never went away just underground, Señor Lopez's from Mexico is the place to go. This retro number was recently spotted on the fashion-mad site Polyvore.
