Thakoon Panichgul! The same New York-based designer who made the dress Michelle Obama wore after her husband's acceptance speech during the Democratic National Convention in Denver. The dress is part of Panichgul's 2008 Fall ready-to-wear collection. (So happy the more shapely Michelle did not coordinate the dress with gray leggings, black lace-up heels and gloves. That model looks like an emo Jackie O.)
As I said before, I'm not a huge fan of the pattern, but she made it work. The black bow is obviously an accessory she chose to go with to give it a little something extra.
Thank you, reader Vonnie, for the tip!
