2010 Royal Ascot Hat and Fascinator Pictures 2010-06-16 07:00:00

If you remember Eliza Doolittle's debut at Royal Ascot in My Fair Lady, then you know all about this classiest (and flashiest) of British horse races. The Kentucky Derby gets its wild preferences for hats from historical Ascot looks, but these days at the UK race, outlandish fascinators and other wild headpieces are much more in vogue. Yesterday marked the Ascot's kickoff, so to celebrate, we've put together 10 of the most creative and dramatic pieces of headgear from the opening day. Check out my favorite ones now.
