Would it be possible to resize the clothes from Growlfshotclothes mod to DMRA size? I would also like to know if it would be possible to merge them onto the residents of Oblivion, much like the ColourWheels mods, after a resize. If someone could point me to a tutorial on how to mod clothes, I would love to take this project on myself. I've looked at some of the links for mod creation and none deal with clothes specifically. Any help would be appreciated.
