Spend a hot day outside and you’re bound to see plenty of men without a shirt on, exposing their nipples to the world. But if women do the same thing, people get up in arms. They gasp. They gawk. And that’s exactly why GoTopless Day exists.

Yesterday, men and women in dozens of cities across the country marched with their nipples on display to point out the ridiculous double standard: We don’t care if men go shirtless in public, but if women don’t cover up, they could be fined or arrested in many places.

Check out photos from the marches below. The irony? You won’t see any female nipples here. Instagram and Facebook deem that explicit content, which can’t be posted on their platforms. So, yeah, we still have a lot of work to do before we get to true topless equality.
