Sen. Hillary Rodham Clinton delivered a message of unity Tuesday night at the Democratic National Convention in Denver. She celebrated Sen. Barack Obama, the candidate she hopes will win back the White House from Republicans in November.

She added, "To my sisters of the traveling pantsuit... thank you."

It’s not only her speech but also those pantsuits that have people talking. According to ABC News, the New York senator is herself being celebrated for a reason beyond her speech. The network reports that Glamour magazine will feature Clinton in a layout that highlights her in several pantsuits. The headline reads: "Hillary, we love your pantsuits."

The hours leading to her speech in Denver sparked more talk about Clinton’s choice of clothing.

While Clinton and her daughter Chelsea surveyed the stage in advance of her speech, so did her aides. They held up pantsuits in different colors. They were supposedly judging which color of pantsuit would best match the speakers’ stage and which pantsuit Clinton would wear for a pivotal campaign speech.

Would she try to unite her party in blue, red, yellow or some other color? She, or they, chose orange.

A pantsuit discussion is nothing new for Clinton. Earlier this year, a Vogue editor wrote that Clinton’s look was too "mannish."

At the Washington Correspondents' Dinner in April, designer Donatella Versace reportedly took a shot at Clinton’s frequent pantsuit wardrobe. "Hillary should wear Versace, a dress, not trousers. She doesn't need to wear trousers to show she's strong," Versace said, according to the TV show Entertainment Tonight.

In February during the primary campaign, Clinton poked a bit fun at herself. During an appearance on David Letterman’s late-night show, she said of the role her husband would have played in her administration, "In my White House, we'll know who wears the pantsuits," Clinton said.

While there are critics and discussions about femininity, the pantsuit is seen as a staple of a modern woman’s wardrobe. There are reports that pantsuits were popular as early as the 1920s. But designer Yves Saint Laurent is generally credited for introducing the modern pantsuit that looked similar to a man’s suit in the late 1960s.
