The First Family was joined by performers including Jennifer Hudson, Victoria Justice and Justin Bieber for the annual Christmas in Washington taping at the National Building Museum in Washington, DC last evening. On the style front, Mrs. O donned a festive green dress with criss-cross neckline. Silver pumps completed the look.
Update: Mrs. O wears a custom forest green crepe dress by Cushnie et Ochs, inspired by the design duo's Spring 2012 collection. The label is designed by Carly Cushnie and Michelle Ochs, who were recently named finalists for the 2011 CFDA/Vogue Fashion Fund prize. You'll find more background on their website and Tumblr.
