I created versions of the skin for medium and dark skin tones. Harder than it looks.

As consolation for my distractedness lately, here’s a skin for your Sim-img needs. It’s the Blogger t-shirt (modeled fetchingly here by Meg) and black pants. Now your sims can be the geekiest on the block! (I forgot, however, that the actual Blogger t-shirt is blue. Mine is black. It’s a limited edition!) Extract to your sims\GameData\Skins folder.
