SOLVED
Hey all,
I currently am using Deacon as a companion. I really enjoy his character, especially when he changes disguises on his own. I accidentally had him equip some clothes and ever since then he will not change disguises. I had him equip his normal "default" clothes(the white shirt) but he will just keep wearing those. ALSO, strangely he seems to equip another of that default clothes on top of the others, making him look fat and making it look like he has long sleeves that look like arms with seems... So, if anyone has some insight on how to get him back into his original disguise mode that would be fantastic. Thanks!
EDIT: I'm on PC so Console Commands are an option, Thanks.
