Alber Elbaz’s long-awaited Lanvin Hearts H&M line transformed a flower-bedecked runway at the posh Pierre Hotel into a major fashion affair last night, as the designer sent out 20 drool-worthy looks from the sweet and sassy line to wow his guests, including Emma Roberts and Sofia Coppola. The lavishly styled models even sported pieces from the accompanying menswear collection, designed by Lucas Ossendrijver, the menswear designer at Lanvin. The line doesn’t hit stores until tomorrow morning (expect long lines!), but you can bid on the featured looks on H&M’s Facebook page along with five of Elbaz’s sketches with 100% of the proceeds going to the H&M UNICEF All for Children Project. Bidding ends on November 26. Prices for the line range from $40 for an embellished T-shirt up to $250 for party-worthy dresses.
