Today is National Gun Violence Awareness Day, and everyone from Barack Obama to Kim Kardashian is participating in the #WearOrange movement to bring attention to the cause.

Amy Schumer, a vocal advocate for the cause, knows there is one thing that always gets attention: butts. And so she posted a selfie wearing just an orange sports bra. Well, she says it's orange. It looks more pink in the photo, but that might just be the filter.

The issue became personal for her after a gunman opened fire during a screening of her movie, Trainwreck, and two people lost their lives. Since then, she's been working with her cousin, Sen. Chuck Schumer, to fight for new gun control legislation. 

Schumer also Instagrammed a couple photos of her wearing a color that is definitely orange, like this shot from Trainwreck.
