Lots of Poser 4 clothes will work in Poser 3, as long as they don't need a P4 garment as a base. Take a look at my site, which has more advice on this and also a links page. From memory, clothes made by Ghastley, ISO, Two-Sword, Sergemarck, Jim Burton, PhilC and Nerd will all work. Some don't - you just have to be prepared for Poser to crash occasionally, so make sure you save before trying a newly downloaded item! Better still, try it out in a new document first.
