Dunham has been supporting Clinton all week, making stops in Iowa and New Hampshire with the Democratic presidential candidate. On Friday, she had the honor of taking over Clinton's Instagram account.
"Hey y'all! I made it to New Hampshire and I'm thrilled to be taking over the HRC Instagram! Warning: I'm pretty focused on my outfits," she captioned the photo, which shows her in a red, white and blue sweater dress by All Knitwear with blue tights and a white beret.
In another photo posted to Clinton's account, Dunham -- who didn't receive any Golden Globes nominations this year -- is seen giving a feminist pitch to attendees alongside former Olympic soccer player Abby Wambach about why they should vote for Clinton. "Campaigning with dream babe @abbywambach!" she wrote.
"Love meeting and talking with the brilliant women of Portsmouth, NH!" another caption read.
That wasn't her only Clinton-inspired outfit, however. She also rocked a bedazzled "Vote for Hillary" blazer, a "Hillary" sweater dress and a custom-made dress screen-printed with "Hillary" all over it to various stops on the campaign tour.
"As a newly grown-up woman who has experienced my fair share of backlash, public shaming and of puritanical judgments, that really moves me," Dunham said to a crowd in Iowa City, about her admiration of Clinton's ability to fend off sexist attacks over the years and her commitment to standing up for women and girls.
"Nothing gets me angrier than when people say I'm voting for Hillary Clinton simply because she's female," she continued. "It's as if I have some feminist version of beer goggles. Let's call it estrogen blindness."
