It’s been a long while since I saw any of the SL bloggers discussing the basic Linden Labs created starter avatars. In fact, in one of the groups that I belong to there was a long discussion about even using a standard AV (as I think you all know, I like my standard AV, I find the mesh versions to be too idealised for my preferences.)
So here we go, I’ve tried on a bunch of the standard bodies so that you can see what they look like. It’s a heck of an improvement on the White Tee and Blue Jeans from back in the day… (And yes, the horse is actually part of the costume for the page riding the horse. It and the wings are ways that LL demonstrates Bento.)
If you want to give it a try yourself, just go to Me > Choose an Avatar in the menu (Standard Viewer). There’s plenty more to choose from, and they’re all actually quite low complexity too!
