Aw, how cute. A Hit Girl dog costume! I found this wonderful tutorial on Instructables.com that shows you how to make one yourself!
Now all we need is a Big Daddy costume for a cat.
The total cost for the materials was $15. I got the skirt at a second hand shop and bought the fabric out of the remainders bin. The black fabric for the mask and cape should be stretchy sports fabric. You don’t have to do any hemming and the fabric has a little “give” to it for doggie comfort. You can buy vet wrap at any horse tack shop and some pet stores.
