The $1,500 brocade dress Michelle Obama donned for her husband's swearing-in got high marks from fashionistas, but the jury was still out last night on the one-shoulder, Grecian-style gown she wore to the Inaugural Ball.

Michelle emerged yesterday morning in a sunny yellow sheath and matching coat from Cuban-American designer Isabel Toledo, complete with a jeweled collar and clever use of tulle, pashmina wool lace and French silk for warmth.

A bold choice, but it worked.

"It was a perfect look from head to toe," said Peter Ishkhans, host of The Style Network's "Peter Perfect." He said everything about Michelle -- from her polished blow-out to her unexpected green pumps and matching gloves -- was spot-on. The outfit was a breath of fresh air compared to previous looks worn by first ladies. And by previous, we mean ... beige.

"We're so used to stiff twin-sets and pearls, but [Michelle's] look had just enough edge," Ishkhans said. "It gave the youth something to identify with."

At about 8:15 p.m., Michelle emerged in an ivory gown, designed by Jason Wu -- a departure from her signature jewel tones.

Also refreshing were the newly minted first daughters, both looking comfortable and cute in age-appropriate coats from J. Crew. Malia, 10, wore deep periwinkle, while Sasha, 7, fittingly wore punchier shades of pink and orange.

"We wanted to offer a collection that would not define them, but one that would let their own personalities shine through," said Jenna Lyons, creative director of J. Crew.
