The original mod was made by Tsar. Check it out. (@bald_king on Twitter)
You do not need the original. Flat and bulge versions available. This version is not as elaborate as other lovely upscales of the same outfit already out there, but it was a fast project I thought I'd share - there are some toggles available, but not a lot!
Tsar / TBSE perms supercede my own. Just don't be a cunt.
