There’s been the usual streak of great new girls on the New York runways this season—Ilva Heitmann, Kirsi Pyrhonen, and Stephanie Rad among them—but one unfamiliar young model with a few key bookings is actually a returning star. The 21-year-old Santa Fe, New Mexico native Arizona Muse—real name, apparently—first caught casting directors’ eyes back in ’08, but she took a few years off to have a baby. She’s back in a big way for Spring ’11, though, thanks in part to her chic, ragged little bob. Most models avoid short cuts, but Arizona’s a perfect example (like Tao Okamoto and Irina Lazareanu before her) of models whose crop tops have been key to their success. This season, Muse bagged Marc Jacobs (and Marc By), Proenza Schouler, Altuzarra, Narciso Rodriguez, and Isaac Mizrahi, among others. With a résumé like that behind her, Europe may well be in the cards.
