My puppy in his Robin costume

Here is my baby, Pudge, in his over-sized Robin costume. I bought him a size medium and after I tried this on him (and had no way of returning it or switching it for another size) I found out he needed a size small It only looks like it fits him because I fortunately got him to sit still and he let me use safety pins on the outfit to pull it back- it was actually so droopy that you couldn't see his feet.
