>> Curious to see what the House of Dior puts out without a creative director at its head? The Fall 2011 Dior couture collection, which debuts in July, is being produced just that way — by the design studio alone — but a peek at what they're capable of came last night. Melanie Laurent debuted the Dior studio's first foray without a head designer — a couture gown inspired by an archival piece — for the Cannes Film Festival opening festivities. See that dress, plus Diane Kruger's slinky Calvin Klein Collection number, Rachel McAdams's peekaboo sheer Marchesa gown, and more from the first two days of Cannes in the slideshow.
