Want the dazzle and pizzazz of the first lady's fashion? There's an app for that.

Michelle's Style List documents Mrs. Obama's most notable wardrobe choices and tells users where to find a dress to match what she wore or a similar option.

At the White House Correspondents' Dinner last weekend, the first lady touted a black cap-sleeve dress by Monique Lhuillier, very different from the floral Naeem Khan of the year before. Michelle's Style List tells users the new dress was custom made for Michelle and offers options for how to create a similar look, from a "strapless trumpet gown" to a "shirred lace/tulle gown" with a plunging neckline.

And if you thought looking like the first lady would cost an arm and a leg, think again. All of the options listed for Saturday's Correspondents' Dinner dress are under $700 - less than the national average cost of going to the prom.

The app's creator, Helen Barclay, is also the brain behind Kate's Style List, a similar app for British style icon and Duchess of Cambridge Kate Middleton.

The only downside to the app is the slight cultural disconnect that comes from its basis in Britain. The site displaying a look-a-like for the Michael Kors dress the first lady wore for the medal of honor ceremony at the beginning of the month lists the price in pounds instead of USD and defaults shipping to the United Kingdom.

The app, which launched April 9, has an archive that lists nine of Michelle's outfits, including the slinky silver number that prompted an Iranian news agency to photoshop a modest neckline and sleeves onto the American first lady in February.

That dress was a one-of-a-kind, and look-a-likes will set you back anywhere from $4,000 to $9,000.
