Bras and underwear. I've gone through and done about 7 pieces and was going to put it out as a mod, but if someone else beats me to the punch, thank you!
I don't think the camisoles will work because there is a part that kinda wrinkles/pooches. I haven't been able to use alpha on anything with a mesh like that, so far.
Edit. Now that i think of it, the cami's might work. The comment on them being a bitch to model got me thinking about it more....
