( InStyle ) -- I ca n't find it anywhere in the Constitution , so maybe there is a first lady dress code buried in an obscure addendum to the Voting Rights Act of 1965 , since every mistress of the White House for the last four decades has chosen a wardrobe that follows a particular one with near pathological devotion . President Obama and first lady Michelle Obama arrive in Prague , Czech Republic , in early April . No sooner does her inaugural ballgown get spirited away to the Smithsonian , then out it comes : The First Lady Suit -- that tailored , multibuttoned blazer over a skirt straighter than an Ionic column in a primary , patriotic or tastefully unobjectionable color . So did someone not give Michelle Obama the memo ? Because during these first 100 days , our newest first lady has banished every version of this silhouette as if they were all designed by the House of Dick Cheney . Instead , Mrs. Obama has defined with remarkable acuity what flatters a tall , broad-shouldered and curvaceous working woman who knows exactly who she is and where she is going . With an enviable eye for color and layering , she has fashioned a riveting parade of on- and off-the-shoulder dresses , cardigans , cinched trenches , leggings , wide-legged trousers and full skirts , working them in intense florals or unexpected hues such as chartreuse and emerald . InStyle.com : Michelle Obama 's first 100 Days of style . In addition , like every woman who gets a kick out of dressing up , she knows the power of accessories -- a cool flat boot , a wide belt , a statement necklace . The thrilling result ? Women across this country ( and the world ) are exclaiming almost daily , `` Look at that print ! I love that color ! Where can I get that sweater ? '' Watch how the first lady has become a style icon » . What 's more , not only does our first lady proudly stride with the confidence and warmth of a modern American woman , but the wardrobe she steps out in boasts relevance , comfort , and -- dare we say it ? -- sex appeal . InStyle.com : Try on Obama 's hairstyle . The fashion industry may have occasionally sniped , but come on , does anyone really give a damn if it 's appropriate to wear a cardigan to meet the queen ? What does count is that each time we 've caught that man of hers watching her walk into a room during their first 100 days , we have witnessed both a dynamic new first couple -- and a wife whose husband unashamedly only has eyes for her . The clothes are cool , but even better is the fact that Michelle Obama has brought romance back to the White House . Get a FREE TRIAL issue of InStyle - CLICK HERE ! Copyright © 2009 Time Inc.
