We love it when girls steal their boyfriends’ clothes (or shop in the men’s department), because there’s something subtly sexy about taking masculine clothes and putting them on a woman. This cozy organic cotton V-neck achieves that look with its screen-printed nod to a bow-tie that’s come undone. And you can feel good about buying one—a portion of the sales from Quiksilver’s eco-friendly apparel goes to E.P.I.C., an organization that helps bring clean water to villages in Tanzania.

We’re giving away five small Quiksilver Eco-Friendly V-Neck Tees, but you have to work if you want a shirt. The five best commenters for this coming week—from today, Friday, Nov. 21 through Thursday, Nov. 27—will be awarded with one. So, be as clever, smart, and original as you can!
