Just to add this is happening to me on PS4 EU
Put a costume on, 2 seconds later I have a heavy armour head and shoulder. Or I change my gear and it puts the outfit on. I have to go into the char screen, turn outfit on, then off again, despite it being off in the first place. Use a wayshrine and it comes on again.
Still happening to me. This is extremely annoying. Part of the reason I play these games is for the look. That is the reason I quest and etc. Maybe that is stupid to some people but it is important to my game immersion. Please fix this issue.
I just wanted to add that after I load then try to switch my outfit off, it won't switch off at all so then I am stuck wearing the outfit for a while until it finally will let me switch it off. Is there a way to get rid of my outfit entirely? This is something I constantly have to fiddle with while playing because I do not like how my outfit looks.
My solution thus far has been to wear a costume. But I should be able to chose what I wear.
