@Whissia , try the next things:
-If you have installed additional mods (other base underwear mods, outfit replacements, etc) on "BnS\contents\Local\NCWEST\ENGLISH\CookedPC\mod" and/or "BnS\contents\bns\CookedPC\mod" please remove all and install again only this mods and test.
-Try a game repair if the first step doesn't help.
NOTE: if that doesn't help i need more information, what client region are you playing (NA,EU,KR,etc.), are you using official launcher or bns buddy.
It's working now, it's just really well hidden on my gon is all.
