American Idol and Dancing With the Stars may have wrapped up this week, but we still have a place to get our competition-show fix—So You Think You Can Dance! The series kicked off its eighth season last night, where stylish host Cat Deeley (left) returned to preside over auditions. “Fashion should be fun and individual,” Deeley told the L.A. Times this week. “I try to be aspirational but also attainable. I might wear earrings from Top Shop if I like the look of them, and I don’t mind wearing things twice—I think everybody does it.” Of course Deeley isn’t the only T.V. host with memorable style. We’ve rounded up our top picks for the most fashionable television personalities, from Project Runway‘s Heidi Klum (center) to American Idol‘s Jennifer Lopez (right), these ladies (and men!) keep us tuning in every week. Click through the gallery to see hot hosts like Ivanka Trump, Tyra Banks and more!

Back in February, we were treated to a preview of Rachel Zoe’s clothing collection, and this July we’ll finally be able to wear it! A slew of stores, including Neiman Marcus, Bergdorf Goodman, Nordstrom, Saks, Blomingdale’s and Shopbop.com have picked up the line, and the stylist-turned-designer couldn’t be happier. “It was this dream that I never thought would be reality because I was petrified,” Zoe told WWD. “I feel so complete now becoming a designer and having my son. I’m the happiest that I’ve ever been in my life.” The launch is timed to the season four premiere of The Rachel Zoe Project, which returns to Bravo in July. And that’s not all the busy new mom is working on—she’s also planning a jewelry line for fall 2012! “I wish it were for spring,” she said. “I am dying to do jewelry. I’m gagging.”
