Textures from the original mod are required for this mod to work properly.
Ane and I collaborated on the AB Uniform together. I made the shirt and Ane made the skirt. Being a mod I helped create, I wanted to port it into the body type I use too, so here it is for Tight&Firm Gen3!! Though actually the chest size is Koneko's TF Gen 3 Vanilla. The legs are regular TF3 Large.
I know this is a pretty rare and extinct body type these days but that's what I plan to continuing making mods for! I have a large collection of other mods I've made that need polishing up but are otherwise ready to be released. Stay tuned!! ^^
