The Obamas have been drawing heat for their 17-day Hawaiian holiday, estimated by some media outlets to cost taxpayers $4 million.

But the criticism doesn't stop there. Now first lady Michelle Obama is under scrutiny for her high-end fashion choices.

For the Christmas Day church service at the Kaneohe Bay Marine Base, Mrs. Obama was photographed in a seemingly simple white sundress with red and yellow stripes. The dress, however, was by French-born, U.S.-based designer Sophie Theallet, and would have cost the first lady almost $2,000 when she bought it in 2009. More recent designs by Theallet sell for even more.

For the meet-and-greet with service members and their families in a nearby mess hall later in the day, Mrs. Obama dressed down - in a printed green $950 Comme des Garcons skirt with bag waist.

Some see the first lady's penchant for expensive labels at odds with her reputation as a bargain shopper who frequents J. Crew and Target.

One comment on the Naked DC website read: "She claims to be a champion of the poor and a fellow bargain shopper, but yet, here she is, sporting a dress that no unemployed American can afford."

President Barack Obama's dinner last night with the first lady and friends was similarly out of range for many Americans. The group dined at Alan Wong's Restaurant, an upscale eatery that specializes in Hawaiian Regional Cuisine and is a favorite of the first couple.

The Obama party ordered off a special 5-course tasting menu for $75 a person - $105 per person with wine pairings for each course. Highlights included"Sassey Salad" and bacon-wrapped pork loin, one appetizer and a sample of three butters from three local dairies.
