Sexy Instagrammers from all over the world are taking photos of themselves topless while on vacation. The Topless Tour Project began in 2012 by Olivia Edington, Lydia Buckler, and Ingvild Marstein Olsen, two Brits and a Norwegian, all in their early 20s, all pretty hot themselves.

The creators said their project wasn't started to be controversial. According to Edginton, the photos are symbolic and about opening your heart to the world. "The Topless Tour is the opening of your bare chest and heart to the world. Everyone is very proud of the message, our parents think it's really refreshing for young women to be embracing who they are and love for their body," she said.
