Upscael of Kate's Gown by TRAUMA to RUEXB with options for RUEXB or MegaCrushers legs* with buff options for each. *(no EXQBRue this time because I have to manually resculpt the dress for each leg size).
Standard long dress rules apply; don't look too closely at how the legs move, and they will clip and deform in some poses. The little decoration on the thong will also just clip/disappear into your ass at larger C+ scales. It's either that or it turns into jelly. The thong strap will also sink into your ass and get funny at larger C+ scales. Don't know how to fix that.
