Rare
OG looks. Same account.
Local Black Knight does not make you OG on paper. It makes every screenshot look like you are.
Why people do it
Screenshots, private creative, curiosity.
Why people regret it
Clips used as “proof” in trades, then a ban talk.
Legacy meshes
Very old outfits can T-pose on new mannequins until the tool catches up.
Does it raise item shop value?
No. You cannot sell a look on your PC.
