We've purchased a yoda costume (too big) and a chicken costume (too small), and a dracula costume (too small). We finally settled on something that looks very cute but we needed a couple of things to pull the costume together so we went to Petsmart.
Arliss hated Petsmart. I am not sure why but he wanted to be carried through the store. I am guessing that he doesn't do "chain stores". I can't imagine why he didn't like it there.
