On my second visit to Second Life, I began to notice the wide diversity of shapes sizes colours and species of fellow inhabitants: Winged, fiery, ghoulish, punkish, cute, normal, and in a few cases, large, hairy and stark naked.
Nudity seems to be frowned upon generally in SL - at least in the places I've visited. Billboards ask citizens to stay clothed. It's nice to know some things are just like the real world.
I suspect that SL probably has a nudist habitat or a "porno land" where nudity is a hard and fast requirement, but I have not yet found seen it in SL.
So, I just ended up doing the same thing in Second Life what I usually end up doing in Real Life:
