I love a glamorous fashion event, especially one that calls for party frocks from one of the world's leading designers as the dress code. Vera Wang opened her new LA store last night with help from a star-studded crowd. As always, they didn't fail to impress. Renee Zellweger chose to show off her toned arms — as always — in an aubergine strapless dress, while Reese Witherspoon followed suit in a satin purple variety. Nicky Hilton looked ultra-gorgeous in a pastel pink dress, and Rachel Zoe chose a dramatic one shouldered number in two tone black and white. Loves it. For all the glitz and glamour, check out our gallery.
