I go to the other extreme. I have almost all of Warlokk's body shapes installed, along with several variations on many of the skin tones for each. I like lots of variety among my characters.
The drawback that I see is that if a clothing item is keyed to skin tone rather than to the body mesh, then a 34dn34 Tanned Light gal wouldn't see the same clothes as a 34Dn34 Becca gal even though they would both fit perfectly.
