Sophia Bush works out a cute pumpkin-colored BCBG Max Azria dress at the grand opening of the W Atlanta Buckhead Hotel on Thursday (January 22) in Atlanta, Georgia.

The “country club chic” interiors for the hotel were designed by Thom Filicia, former star of Bravo’s Queer Eye for the Straight Guy. The 39-year-old celebrity interior designer said, “The whole concept is about Buckhead’s upscale elegant lifestyle, which has a cachet about it … the hunting and fishing is part of the fabric of the South, or at least the people I know. They love the outdoors. And Atlanta is a really beautiful, urban sophisticated town with great shopping and food and interesting culture, so it’s the combination of those things. Let’s take that lifestyle, that point of view and that aesthetic and let’s connect it with W, which is very modern, so that it will give this hotel its own look and feel that’s very specific to Buckhead.”

Also pictured: actress Michelle Trachtenberg and The City star Olivia Palermo.
