Michelle Obama Wears Pant Suit, Flats To Wednesday Night Dinner (PHOTOS)

The Obamas held their largest Wednesday night event to date at the White House, this week hosting a dinner for 200 guests. Among them were Congressional leaders and their spouses, Vice President Joe Biden, Treasury Secretary Timothy Geithner, and White House Chief of Staff Rahm Emanuel (both of whom were just nominated in our "Who's The White House's Hottest?" poll).

The menu included celery soup, mushroom crisps, steelhead salmon, saffron couscous, crispy spinach and greens, with milk chocolate velvet cake for dessert.

First Lady Michelle Obama went a little more casual than she did at last Wednesday's event--a concert honoring Stevie Wonder, where she donned an emerald dress designed by Wonder's wife Kai Milla--wearing a black velvet pant suit, large brooch, and flat black shoes.
