First Lady Wears Barbara Tfank Dress at State of the Union

First Lady Michelle Obama sported a sapphire blue dress by Los Angeles-based designer Barbara Tfank for the State of the Union address.

The designer described it as a “criss cross bodice cap-sleeved slim dress in silk twill.”

Mrs. O also wore Barbara Tfank — a floral print dress from the resort collection — last May for a Buckingham Palace visit where she greeted the Queen and met Duchess Catherine (aka Kate Middleton) for the first time.

The designer, who started her career as a costume designer and has said that her focus is on creating “timeless” looks, will show her latest collection during New York Fashion Week on Feb. 13. Tfank’s spring 2012 collection was inspired by some of Elizabeth Taylor’s most iconic on-screen styles.
