We've made no secret of the fact that we love the Olsen twins' style. Their look is very much in the school of oversize jackets and sunglasses, but it's always so chic. Their eye for fashion has been translated into not one but two very stylish labels—The Row and Elizabeth and James—not to mention countless collaborations.
The fashion industry has also taken note, with the CFDA awarding the sisters label of the year in both 2012 and 2015. Last night, the twins added a further milestone to their designing careers, by celebrating the opening of their Elizabeth and James flagship store in L.A.
Of course, there was a guest list full of impeccably dressed celebrities who attended the event at the iconic Chateau Marmont. But first, we should note how much we loved Mary-Kate and Ashley's outfits; MK donned a black dress and coat whereas her sister was in a cream version. The eagle-eyed amongst you will also note how Ashley's shoes matched her sister's bag.
As for their guests, many were decked out in the latest looks from their label, as well as some pieces from the upcoming season. To see all the best outfits from last night, click through our gallery.
