A wacky pajama costume, this time for adults!
This onesie type 'pj character costume' is for adult sizes only. It's classic type, with the usual Sonic 'half a face' hood & zip front. Unlike others though, this one only includes the nose and doesn't add any of the lower face (beige part) at all. It also seems to be missing the blue borders for the ears which isn't a good look. It has stuffed spikes for the back of the head/hood, and for the photo they're pulled to the side so you can see them. (They'd lay in the back normally like all of this type do. The long sleeves are beige & it has the 'lower crotch' cut but not the bag-style cut (where the pj looks like a sack with the crotch area at the knee level)

This probably is only good for a novelty use though. The hood isn't removable so sleeping with floppy stuffed spikes and a hood that can twist around your neck probably isn't comfortable. Ironic wear at a 'wacky pj party' or something would likely be the only use for it.
