Hi! I just downloaded your workers set starter pack yesterday and I'm enjoying your NPCs' stay at my sim's home. Can't help but notice ('coz I have a nude patch on) how nice and anatomically correct your skins are. Is there anyway I could download your skins (would love it better if it has defaults)?

By the way, I brought Claudia Golden to clean in Sims State University, it's funny 'coz she also researches and does assignments just like any other student and yet never fails to do her duty. Now my dormitory is spic and span.

The reason for this is: the workers are Young Adults, and they are University attendees in their spare time.
Danny will have to reply to the other half of your question.

Sorry, but answer is no.
Reason is simple: skins used for NPCs are not full skins set, so there is no easy way to use it for your own sims.
