The Emmy winner also tweeted that she is thinking of the 'Trainwreck' victims every day.
Amy Schumer knows how to draw attention to a cause that matters to her.
The Emmy winner shared a selfie of herself going bottomless in an orange sports bra on Thursday -- knowing that a NSFW selfie will get picked up by the media and help spread her message about gun control.
"Today please #WearOrange for gun safety," she captioned the photo, tagging Everytown, the movement that organized this campaign to recognize National Gun Violence Awareness Day.
Suffice it to say, it worked: check out Everytown's mission on their website here.

Gun control became a very personal matter to Schumer when a shooter opened fire in a theater screening her movie, Trainwreck, in Lafayette, Louisiana, last July, killing Mayci Breaux, 21, and Jillian Johnson, 33, and injuring nine others.
"Me and my honeys on set like to #wearorange thinking of you today and everyday Mayci and Jillian," Schumer also tweeted.
The Inside Amy Schumer creator has spoken out for stricter firearm regulations a number of times since the tragedy, including a press conference last August with her cousin, Senator Chuck Schumer, where she said, "These shootings have got to stop. I don't know how else to say it."
