Good plan!! :) I think it would be a lovely skirt BTW. I like gored skirts, very feminine, and flattering to almost any body type.
Stay away from dupioni and shantung for this skirt. They would be too crisp and stiff. Although, a nice tailored blouse out of dupioni for the top half would be gorgeous. :) Acid washing will soften it a little and make it machine washable for the rest of its life. I did a blouse just like that for a pal of mine around Christmas time in '06. Looked great.
I think for the skirt it would be Gorgeous to find a print crepe de chine then line it with China silk (habotai.) The only drawback to that is it might be a little clingy. But some anti-static spray will usually take care of that. The drape on that would be sooooooo pretty. Again, I would acid wash (if it's not black; black tends to fade too much) just to soften. That's hot water in the washing machine with 3 cups white vinegar added. In the dryer till bone dry. Some of the China silk I've seen lately is so Crisp that I wouldn't think about using it for a lining or lingerie, etc. without this treatment first. (it's great when it's crisp for lining things like bodices, etc. just not flowing floaty stuff.)
Also, you might keep your eyes peeled for some nice rayon. Like a rayon challis. That can be Lovely to work with too. And the Bemberg rayons, are great for linings. (those can also be acid washed; the result is what my mother would call "wind pudding and air dip." Just really scrumptious feeling--very very close to acid washed China silk.)
If I spot anything that sounds like what you're looking for, I'll email you a link. :)

I've started a new Thread on this since I lost the other one on my computer. I copied your entire post Sharon for my benefit, Thanks for your input. I've been looking for a print in Crepe de Chine and haven't seen much yet. I'd like to stay with a dark print if possible, I think they are pretty. I have seen a couple of nice ones in rayon on Fashion Fabric Club but never having bought from them I have no clue as to their quality. I'm really looking to look good when we go to dinner with the children. BTW the 2 oldest grandchildren will be there as well. We have a date for June7th so as I said before I have plenty of time to plan and get going on this.I appreciate it that you will also look around for something for me. Juno
