Actually a better place to start would be here:
http://warlokkstower.googlepages.com/bodyshapeguideThe Bodyshape series does not replace ANY default outfits, everything is custom from skintones to clothing... this allows them to all exist together in the game at the same time, while not eliminating the default Maxis size and all the clothing made for it. However, there are currently only 8 full-body outfits and about a half-dozen tops and bottoms for each size. There are many, many recolors for those outfits though, mostly found in the Hi-Res section here.
