You should make sure the clothing you want to conform is the active figure. Make sure it's the item you see listed underneath the main window. As for fitting clothing made for other characters...I'm afraid that's not easy. That's why people buy clothing in the MP here. :-) For still images, you can often fudge it with scaling and careful use of camera angles. For a true fit, or for animation, you'll have to buy special software and learn how to use it. If you're new to Poser, IMO you'd be better off putting that money toward the Victoria figure sold at DAZ. They have a special promotion running now that will get you 30% off the list price. If you don't want to do that, register at DAZ (it's free), and eventually they will offer you the low-res versions of Mike and Vicky for free. You'll be able to use clothing made for Mike and Vicky 1/2 with those figures. In the mean time, you might want to use the P4 figures (Dork and Posette). They come with Poser 5, and there's a lot more freebies for them. For a variety of reasons, the P5 figures have never really caught on.
