After Nastia Liukin won gold at the 2008 Olympics she didn’t go to Disney World, she went to New York Fashion Week! Now, the style-obsessed gymnast (who served as the face of BCBG MaxAzria’s Spring 2009 collection) is set to debut the Supergirl by Nastia clothing line, which hits JCPenney stores nationwide tomorrow. “I’ve always been into fashion, but when I was training seven hours a day, six days a week there was just no time to pursue it,” Liukin told us. “And everything moves so fast in the fashion industry!” The collection of dance wear, dresses and super-girly pieces like leggings and shrug tops is aimed at the back-to-school set. “My fan base is mostly young girls and I wanted to use the line to inspire them,” Liukin explained. “At the Olympics I did my routine on the uneven bars to the song ‘Supergirl’ by Saving Jane and when it came time to name the collection, I thought, ‘What better way to feel empowered than to wear the Supergirl shield on your clothing?’” Liukin is still weighing whether or not she’ll compete in the 2012 Olympic games, but if she does, she’ll still be putting her fashion sense to good use.  “I design all my own leotards,” she told us.
