I’m sure it was a combination of tastes/comfort expanding, but tumblr had a lot to do with it. Pre-tumblr I was victim of the stuff we have brow-beaten into us about bodyhair (especially on women) being icky. Now I’ve really embraced bodyhair. And it seems into everything like character design (e.g. my male characters aren’t all miraculously smooth any longer) and sim making (bodyhair overlays = win).
