Stock up now—tutus just might be one of the hottest trends for spring (point shoes not required).According to The New York Times, Kate and Laura Mulleavy of Rodarte (who created the costumes for Black Swan) aren’t the only designers with ballet on the brain. Pieces from the spring 2011 runway collections of Karl Lagerfeld, Alexander McQueen, and J. Mendel included everything from poufy miniskirts to shredded fabrics and feathers (sounds dancer-esque to us!). Plus, stores likeBloomingdale’s and ASOS are already selling the ballerina skirts. Not to toot our own trend-spotting horn, but we sort of saw this coming from a mile away. Remember?! And now, celebs including actress AJ Michalka, singer Katy Perry, and model Jessica Hart are rocking the tutu like it’s going out of style. But it’s not!
