Whether she’s rubbing elbows with dignitaries, mucking about the garden, yucking it up with late night hosts, or rocking a hula hoop, Michelle Obama always does it in style. Check out her hottest looks from 2012 — worn while on and off the campaign trail. (Photos: Getty Images)

Is the president shocked at how striking this dress is? The first lady must have made a big expression when she wore this Barbara Tfank number (for a second time publicly) to host the first ever Kids’ “State Dinner” luncheon at the White House. (Photo by Alex Wong/Getty Images)

“So nice, she’s worn it twice” should be the tagline for this Chris Benz Floral linen dress. It was first worn by on Obama “Extreme Makeover Home Edition,” and again recently when she spoke to a crowd during a campaign stop at the Barbara Goleman High School in Miami Lakes, Florida. In these tough economic times, it’s nice to have first lady who is proud to sport the same outfit more than once; plus we love her in this feminine dress. (Photo by Joe Raedle/Getty Images)

This regal blue off-the-shoulder Marchesa gown was the perfect choice for a State Dinner with British Prime Minister David Cameron and his wife, Samantha, last March. We love how she tops it off with one of her signature looks – the bold necklace. (Photo by Mark Wilson/Getty Images)

The first lady wore this smart and sassy Porsha dress in Cable Squares Lime and Cable Squares Mink from the Diane Von Furstenberg Resort 2013 collection the day before her big convention speech. The color blocked heels are paired with this ensemble to perfection! (Photo by Joe Raedle/Getty Images)

Michelle Obama looks cool, calm, and collected in a white Thom Browne sheath (a style that works so well on her), for a White House luncheon celebrating the 2012 honorees at the Cooper-Hewitt National Design Museum’s annual awards. (Browne took home the award for his contributions to fashion.) Obama threw on an Alexi Bittar statement necklace for a pop of color. (Photo by Mark Wilson/Getty Images)

Mrs. Obama wore this perfectly flirty — yet prim and wifely — ASOS Midi Dress in Check Print for a stop on the campaign’s bus tour through Iowa. Midwestern chic! (Photo by Scott Olson/Getty Images)

First Mom Michelle Obama knows how to have fun, whether she’s planting a garden on the White House grounds or jumping around on stage with a group of kids. Children clearly energize Mrs. Obama — whether her own daughters, Sasha and Malia, or the many kids who drop by the White House for events, many from local schools and military families.

Why not wear a Michael Kors one-shoulder pleated georgette sensation to present the Presidential Medal of Freedom to Israeli President Shimon Peres? Mrs. O looked splendid at this recent White House event, and the vintage Dior belt from New York Vintage was a good move. (Photo: http://www.destinationkors.com)

African American designer Tracy Reese is one of the first lady’s favorites, and it’s no surprise. The designer’s lady-like looks are perfectly suited to FLOTUS. She donned this black and white chevron print dress for a recent fundraising dinner, and she also wore it for a luncheon with the first lady of Britain, Samantha Cameron. (Photo by Leslie E.
