I use the HGEC EBE e-cup body, as it's what I went with for the Eve stock clothing replacer.
The female Sheogorath regalia is a fairly nice mod, but it could use some work-
Part of it is the leg muscles which are bulky. This is a male mesh edited to fit females but could use some tweaking. I am not sure about permission, the author's forum profile says they were last here in 2010, and one of their other mods has "If you use this in another mod please let me know first" in the description but that's it. The author may even be unreachable by this point if they haven't been here in that long.
Its the vanilla Sheogorath clothes, right? I'll look into it, at least.
I'd like to see a version of the E-cup fighter armor with the bikini. The author released the normal e-cup with and without the bikini part, but fighter only without. They give permission in the description.
This should be pretty straightforward.
