Buffalo gals won't you come out tonight? Hipster celebrities are adding edge to their wardrobes with buffalo plaid toppers. "You really have to be cool to carry it off," warns Jesse Garza of styling team Visual Therapy. For those with less fashion moxie, Garza recommends toning down the bright checks with a plain jacket or cardigan, à la Ralph Lauren. Got youth on your side? Just bring attitude and a great pair of shoes. Says Garza, "This [trend] is for someone in her early twenties with a pair of fluorescent Louboutins."
