This costume is super cute on my dog. I bought it so that we could dress up for Halloween, but it may turn into something she wears more often. The t-shirt has Velcro closures along the back of the dog, and the cape ties around the dogs neck.

Super Dog

Cute, a bit big for my dog, but not that bad to take photos in. The colors really pop against my black & tan Doxie's fur.

Great Costume!

Most costumes have head pieces, which my dog refuses to keep on for more than a few seconds. This costume, however, is simple and easy to put on without any fuss. It arrived as described and looked absolutely adorable. Besides, all dogs deserve to be superheros!

Fits well using the sizing chart. It's the pup's first costume and already a ton of compliments (when trying on to check fit). Thanks Baxter Boo!
