Thanks, everyone. I followed the steps above, and got it to basically do what it's supposed to do. There's still a lot of stuff in the cloth room that I don't know what it means. ("choreographed group"?) This is a very simple outfit and I just needed it to drape like cloth, but for future reference I'm wondering what all those controls do.

If you really want to learn how to use the cloth room to it's best effect, I highly recommend the Master Cloth Room tutorial for sale at RDNA.  Esha is a master with the cloth room and makes it easy - including the advanced functions she discusses.  There are 2 sets - one with just the tutorial and one with several pieces of Esha's dynamic clothing.  The tutorial is the same, the higher priced one includes the tutorial and the clothing. I bought it when it first came out and I have never regretted the purchase.
