It's probably one of the outfits you recategorized, so sort by recently edited first.

Update
It IS an outfit causing the issue
I put the skins, accessories, and everything else back with no problem
So I think what I'm just gonna do is delete them all and redownload clothes
It's been too long already, I just wanna play
So I don't wanna pick through
I'll just redownload and not recategorize this time.
Thank you all for putting up with my stupidity and laziness.
