(UPDATE, placed at the head before the page break so everyone can see it: Be sure to read the comments on this post, especially those from Maggie Bluxome.)
I signed on for a bit this morning (RL is keeping me pretty busy these days) and was IMed by Bart Seymour. He'd been talking with Reine, and had some of his mesh avatars on display. We chatted for a bit, and it turned out he was making one model that he thought I'd like. I did indeed, and I bought it on the spot.
He helped me, clumsy as I am, with setting it up. I will have to seek out a pale skin (of the sort I prefer) in texture form; the avatar is set up so that such textures (which, if I understand, are packaged together to comprise an SL skin) can be applied to it--for testing purposes, I used a tan skin. (Let's pretend that I spent some time on one of those nude beaches in SL. :))
I had to tweak my shape to work with it--somewhat broader-shouldered, a little shorter (*sob*). (I made my torso a bit longer, which in SL shortens your thighs. I'll experiment to figure out the best settings, and see what's really necessary to work best with the avatar.) I took some pictures, but having just downloaded the Firestorm FUI beta (more on that later), I hadn't twisted the graphics knobs. Bart was already set in that respect, so here are the photos that he took, behind a break as there are some NSFW mannequins in view:
Alas, I don't think either these or the photos I took show enough detail at a good POV to show off the white thong to advantage. The stock avatar crotch is notoriously bad, and even if you don't care about breast size, improved quality there might be important to you.
In any case, I am very impressed. While the cleavage doesn't extend as near to my sternum as I'd think it should (maybe that's a skin issue...), it's still lovely.
I can't use it full-time right now; clothing is an issue for now. (NOTE: one shouldn't infer from that qualification that I know anything about what clothiers might be doing in that respect. I don't.) Even if I could, I'm not sure I would; I am still very attached to Foxbean Laboratories' breasts. Also, I am on the fringe in multiple respects--am I willing to trade off some leg length, height, and slenderness for the advantages of this avatar (to be sure, some would say that I should)? I don't think I've gone overboard on shoulder width, but I will want to look at the shape I used more closely at my leisure.
