Two gorgeous women, one stunning dress. This is going to be an interesting fashion brawl! Heidi Klum first wore this Louis Vuitton Spring '09 embellished LBD back in '08. She also wore the runway accessories — frilly sandals and stacked bangles. Jennifer Lopez attempted the same dress at Scott Barnes's book launch in NYC. Her accessories of choice are ankle-strap Loubs and a chunky cocktail ring. Both are undeniably sexy, but whose version do you love more?
