How can i fix this cc?

these pants  simblr-outfitters.tumblr.com/post/156500261639/unif-winx-pants-gia-top-welcome-to-the   are causing a nude reaction from sims and after doing some searching i'm assuming it's because it was made from a nude mesh and they didn't change it from the nude category? I don't mod ever and i rarely recolor things, but i was wondering if there was anything i could do to fix this cc and change it's category so it won't get a nude reaction? 


Edit: I fixed them! i used s4s to edit the mesh..even though the nude category wasn't selected. I didn't change a thing, but i saved the "new" one and i used it on my sim and the problem went away. weird..
