What don’t Reese Witherspoon and Renee Zellweger have in common? Both are currently unattached, exceptionally skinny blonde actresses with broken marriages, countless romantic comedies and an Oscar each to their names, and both showed up in slim mini-dresses to the Vogue party for Vera Wang‘s new store in LA Tuesday. If it wasn’t for Reese’s kids and Renee’s workout pants, we’d think they were the same person. Similarly slim stars like Mila Kunis, Rachel Zoe and Nicky Hilton also attended the event, but—with all respect to Wang herself—everyone knew who the big stars were last night. So who’s looking hotter? Check out the gallery and let us know in our TheFABLife poll.
