Hair bows popped up all over the runway during the Spring 2010 New York Fashion Week, and the bigger they were -- the better. Apparently the fashion trend has caught on to some of fashion week's front-row spectators, as witnessed by these starlets who have adorned their heads with bows, from the outrageous to the demure. Singer Katy Perry channeled her inner-Minnie Mouse when she wore this huge red bow to the 2008 MTV Europe Music awards Nov. 6, 2008, in Liverpool. (Jeff Kravitz/FilmMagic/Getty Images)
