It’s a bird! It’s a plane! It’s your favorite silk scarf safety pinned to a leotard!

Save the world, the environment, and your accessories with Earth Hero shirts by Little Capers, which have landed in Miami just in time for Earth Day.

Designed by a mom (in a bid to reclaim her dish towels), the 100 percent cotton tees sport hero emblems and Velcro-detachable capes. For kids sizes 2 to 8, they come in green with both blue and pink accents.

Plus, 5 percent of the proceeds goes to Conservation International. So when you get a shirt, you also do some good.

All in a single bound.

Available at Industry, 18153 Biscayne Boulevard, Aventura (305-705-0032); online at littlecapers.com.
