This is a hilarious costume. We recieved the XL in this costume. The inseam is 34" or so. The arms very long. It would fit a very tall and big man. The waist is elastic, and can go around a pretty big guy, but might need some "adjustment", like cutting it open and adding more elastic. The back of the costume hangs down like a morning jacket, clear to the knees. The ears are a bit on the small side. All in all, if you are willing to give it a good ironing and work with the ultra-long sleeves and legs (or maybe you have long arms and legs which would make this your perfect costume) buy it. It's fun.
