msmcknittington | Lining silk satin?

Dear friends who have much more sewing experience than me (so pretty much everybody on my friends list),

What do you recommend for lining silk satin? (Oh, yes, we have decided on a fabric and my impatient sister is raring to order.) I think for the pattern* we're using, it doesn't need to be too substantial. So it's not like I need to break out the silk organza and cotton twill. I definitely don't want to use the terrible lining fabric they have JoAnn Fabrics, which would be like flinging holy water on a vampire (or a vampire on holy water, maybe?). All the bridesmaids dresses I've bought have had some variation on a lightweight poly even weave -- the good version of the hideous lining fabric.

Would a firm cotton be good enough? The skirt's unlined, and if I needed to line it for body, I'd flatline it, so I wouldn't need to worry about the skirt moving over an underskirt.

Hang a tick, my Vogue Sewing Book says that silk organza is a good lining fabric for silk satin. What say you, best beloved internet friends?
