Dancing aside, the reason to watch "So You Think You Can Dance" is to see what hostess Cat Deeley is wearing. When we caught up with the gorgeous blonde at "LIVE! with Regis & Kelly" her outfit of choice was a sexy, casual black-and-white Mulberry top and Superfine jeans. We were delighted--but not exactly surprised-- to learn that Cat doesn't even have a stylist. Her fabulous mix of high-street, vintage and designer is all her own. She even prefers to do her own hair and makeup. Find out Cat's easy trick for getting her locks to "go all beachy" and hear what, in her opinion, is the biggest fashion faux pas one can make.
