you're right - double click is replacing the selected figure, and "double check" on the bottom ADDs new figure - go figure (hehehe) to conform clothes to figures (characters) you need to choose "conform figure" from the menue. if your character has some individual body morphs or you scale body parts more than just a little, it is most likely that those body parts will pop out of the clothes. some clothes have already morphs to adjust to different character morphs, but mostly the don't. you can turn the protruding body part invisible, though...
