Stylish first ladies who dazzle with glamour

First ladies are in a unique position to advocate an agenda – and look stylish while doing so. Here are some first ladies who have been turning heads.

Other presidents' wives from China have stayed far in the background, but Peng Liyuan is changing all that. The wife of Chinese President Xi Jinping has been making headlines for her personal style and cheering her home base when she opts for fashions made in China. Here, Peng, 50, looks glamorous in a crisp suit while watching a traditional Tanzanian entertainer upon her arrival in Dar es Salaam on March 24, 2013.

Sam Cam is so fashionable that she recently hosted the reception to kick off London Fashion Week and looked great while doing so. The wife of British Prime Minister David Cameron often makes news for her fashion choices. Here, she is pictured arriving at the Erdem fashion show during London Fashion Week on Sept. 17, 2012.

Mehriban Aliyeva is an island of glamour. The wife of Azerbaijan’s President Ilham Aliyev consistently dazzles with timeless outfits and dramatic hairstyles. Here, Aliyeva is pictured at Azerbaijan’s celebration of 20 years of independence in December 2011.

She may not have quite the same name recognition on this side of the Atlantic as Carla Bruni-Sarkozy — France’s last first lady — but Valérie Trierweiler is still garnering plenty of praise for her sense of style. The partner of French President Francois Hollande tends to favor monotone colors, chic blazers and long coats. Trierweiler is pictured here with children at the "Vivre et travailler autrement" (Live and Work Differently) Association in Kinshasa on Oct. 13, 2012.

The wife of current Russian Prime Minister and former President Dmitry Medvedev routinely tops Russian best-dressed lists. She’s pictured here in February 2012 at Maslenitsa, a religious and folk holiday that corresponds with the end of winter.

The hat says it all! Chantal Biya is one first lady who does not shirk her fashion duties. The wife of Cameroon's President Paul Biya is pictured here welcoming Pope Benedict XVI to the African nation in March 2009.

Cool and classy, Daniela Schadt — domestic partner of German President Joachim Gauck — arrives for a premiere at the 63rd annual Berlin International Film Festival in Germany on Feb. 15, 2013. Schadt often wears solid colors, blazers and, at formal events, dramatic gowns.

Here she is, the pinnacle of fashion royalty herself. The wife of U.S. President Barack Obama is known for her effortless fashion sense. Her style and beauty choices are so closely monitored that her bangs can spark a national discussion.
