"I have downloaded a few items from the free section, but I can't seem to make them fit the figures right." A lot of the clothing (and smart props) you find nowadays will be for Vicki and Mike, and won't fit the standard Poser 4 people right off. Look for the older freestuff, especially that marked for "Posette", "Dork", "P4F", "P4M" and similar keywords. Is there something in particular you're looking for?
