Maybe it was the glare from Lady Gaga's mirrored ballgown or the pyrotechnics on that boob flamethrower, but somehow Karen O's stunning outfit at Glastonbury last weekend slipped though our fingers—until now. We're guessing the costume is the work for her BFF, designer and costume creator Christian Joy, whose spring 2009 lookbook features bandana-wearing doggies, Fourth of July fireworks and dresses splashed with lobster print. Karen's headdress of all-seeing hands actually makes us us want to spend the rest of the summer in a teepee on the roof.
