First Lady Michelle Obama's inaugural outfit by Cuban-born Isabel Toledo

A yellow dress by Cuban-born designer Isabel Toledo was chosen by First Lady Michelle Obama to wear on this historic Inauguration Day

Inaug_dish_kds4zpnc_400 "I wasn't surprised at all that she [Michelle] chose Isabel Toledo," Patricia Mears, deputy director of the Museum at New York City's Fashion Institute of Technology, tells Life & Style.  "Mrs. Obama is an unusual woman with great fashion instincts and innate style. And she has always supported lesser-known designers like Thakoon, Narciso Rodriguez and Isabel Toledo."

Michelle accessorized the dress with unusual green gloves from J. Crew and green shoes.

Necessary considerations for her inaugural outfit:

(A) It had to be warm. The upper part of the coat and the back of the sleeve are lined with a pashmina for extra warmth.

(B) Sophistication counts. The fabric and color are also very sophisticated with a layer of lace over wool. The color is called lemongrass.

(C) It's not a suit, unlike most of the other first ladies' outfits.  Mrs. Obama chose a sheath, a style that that skims and flatters the body.

First Daughters Sasha and Malia wore coats from J. Crew. 

Ten-year-old Malia wore a double-breasted periwinkle coat with a blue-ribbon bow at the waist, and Sasha, 7, wore a pink coat, orange scarf and satin belt, a coral-colored dress peeking out at the hem.

What do you think of the first lady's first official fashion choice?
