One of my favorite costume items from Jam Cruise (music fest on a cruise ship, leaves from Miami, look it up it's a blast!) It was part of a Pikachu costume for Yellow Night, and the mesh back makes it breathable which was nice for daytime wear.
Upon my initial purchase I only had the costume in mind, but I ended up wearing it around the boat for the next couple of days since it was a fun and easy way to get recognized by other cruisers. Pikachu, glad I chose you!
