Betsey Johnson has always been a girl who just wants to have fun with fashion, and for her 70th birthday the designer put on an epic bash to celebrate the occasion, as well as a career that has spanned five decades. Cyndi Lauper, who has been a Betsey fan since 1980, performed an energetic set of greatest hits (including, of course, "Girls Just Want to Have Fun") before Johnson sent her own greatest hits from the archive down the runway. Noteworthy throwbacks included a funky orange, wide-wale corduroy "Verushca" set from the sixties, 1980s punk mesh looks, and a Nirvana-era tapestry coat paired with a burnout velour slipdress.

Those vintage numbers set the tone for Johnson's Spring collection, which, as usual, was more about promoting a confident, irreverent attitude than the clothes themselves. Models with teased-out, crimped hair hammed it up for the photo pit. Some waddled around in snorkel flippers and arm floaties, another pushed a toy stroller, and one girl even cradled a baby pig. Those antics put a quirky spin on Johnson's signature corset petticoat frocks and baby dolls. The final 30 looks (out of 90 total) belonged to a capsule of cupcake-sweet birthday "Princess" dresses. Johnson came out at the end and danced around onstage (she also did her seasonal gymnast split) to roaring applause from the crowd. The Betsey Johnson label may have filed for bankruptcy protection earlier this year, but at 70, the designer who built her business around flipping the bird at fashion's conventions shows no sign of slowing down.
