Kyrsten Sinema checked off a couple of firsts as she was sworn in as a senator on Thursday morning.

The Democrat from Arizona became the first openly bisexual person in the Senate, and she’s Arizona’s first female senator. She is also the second openly LGBT person to assume office in the chamber, after Sen. Tammy Baldwin (D-Wis.). Sinema defeated Republican Martha McSally in the November midterms to replace retired GOP Sen. Jeff Flake.

Sinema is no stranger to making history: In 2013 she became the country’s first openly bisexual member of Congress, serving in the House for six years. The newly minted senator was sworn in alongside Sens. Mitt Romney (R-Utah) and Bernie Sanders (I-Vt.).

Aside from her historic swearing-in, Sinema looked very chic, arriving in a pink faux-fur-trimmed coat with a polka-dotted pink purse, then sporting a gray faux fur stole for the ceremony. Twitter, of course, took notice.

“Kyrsten Sinema serving Elle Woods as she joins the Senate today is an energy we very much need to carry on through 2019,” one Twitter user wrote.

Another said her outfit was “an image for the ages,” tweeting, “So loved watching Kyrsten Sinema sworn in as Senator in totally fashion forward outfit with tight skirt, dour men around her looking completely flummoxed, like they’re in some strange new world they don’t understand. So true, and so deeply satisfying.”
