Suit up!

That was the rallying cry for some ardent Hillary Clinton supporters headed to the polls Tuesday to cast their votes. Clinton is famous for her love of pantsuits in a wide variety of colors, and to many of her supporters this season, the outfit has become a symbol of their respect for the candidate and her effort to make history as the first female U.S. president.

Clinton's signature outfit even inspired a private Facebook group called "Pantsuit Nation," which boasts nearly 3 million members, many sharing their voting stories on this Election Day.

Here are just a few of the many pantsuit photos Clinton supporters have been sharing on social media.
