This is a soft, fluffy, and warm dog or cat outfit. The girth can be adjusted with two sizes of buttons. I've put it on a few times, but my pet didn't like it, so I'm selling it. Size (laid flat, measured by hand) [Size is unknown, but it seems like a size M, as it was a little big on my S-sized pet] Neck: 16cm Girth: 22cm (underarm) Back: 27cm - It has been washed but worn a few times and stored by a non-professional. Also, before shipping, I will use adhesive tape again to remove as much hair as possible, but I cannot remove it completely, so please refrain from purchasing if you are concerned. - Returns are not accepted if the size doesn't fit. - It will be shipped with waterproof packaging. If you have any requests for additional packaging methods, please comment before purchasing.
