One hot dress, two hot MILFs. This one's a toughie. Zac Posen's cobalt silk ruffled dress was worn by Demi almost exactly a year ago (June 23, 2008). Cindy wore the stunner June 18 to help launch the new Remington hair straightener. Both ladies wore gold shoes — Cindy's are more fierce, Demi's peep toes are ladylike. They both opted for diamond bangles on the left wrist as well. Demi carried a black clutch while Cindy went hands free. What's your verdict?
