I have seen (and own) some wonderful secondskin jeans, leather pants, haltertops, and t-shirts as well as underwear. They are good for the stated reasons that they are great for figures you don't have clothes for and for figures so big on memory you can't run them with clothes in the same scene. Also second skin gives no poke through or conforming issues and bump maps as well as morphs can give them volume even when they are actually on the figure texture rather than a catsuit. The community acts as though they are doing wall sized renders as the norm, but how often do you see a render where the poly count of V3 or Miki is obviously needed as oposed to saaay... V2 Reduced Resolution? I would like my seams and zippers to be bumped but am I doing 3000x3000 renders of V3 pans fly? Not too often. I like second skin and I definately buy almost exclusivly ApoGraphix from Fenrissa for my textures not just because of the quality of the textures and characters but also very much for the lovely second skin. Bump map for detailing and cuff morphs would be real nice... I have not bought any but I have made some and the results are great... you could even use the default unimesh cuff morphs but making your own would be better.
