There is a quicksuit for the G2 females at Morphography. You can use that as a starting point for making clothing.

Not quite free because it is a subscription site, but Poserworld is your best source for clothing for the Poser 7 characters.

There are two free outfits by Ravenhair at Content Paradise.

Check out PhilC's site, he has some stuff for Alyson.
