Rayon and/or sewing question

As I'm going through clothes to ebay, I've come across some older
rayon items––dresses, blazers––that have sort of sagged or otherwise
stretched (or perhaps shrunken?) out of shape.
I know that a lot of rayon is ruined if it gets wet, but I don't think
these things were ever washed. (They're not *that* ruined.) The
saddest ones are sagging along parts of the hemlines, so the hems look
crooked or uneven. Is this something a seamstress can fix easily?
Has anyone here done this or had it done by a pro?
Does this problem happen just from hanging on hangers, or did I miss
the problem when the clothes arrived from ebayers? Maybe I caused it
by pressing out wrinkles?

p.s. I'm selling some of my stuff, and I'm planning to list new
things daily until my wardrobe is a reasonable size...which will take
approximately forever.

Wow, you have been doing a lot of work. Those red plaid maryjanes are
adorable. I have never found a way to get sagging rayon back in shape but
try to google a few sites to see if there is any help for them.

Thanks, Audrey. I'll have time to google the rayon issue because my
lucky–I–haven't–killed–her deaf cat knocked my digital camera off the
counter, destroying it. I can google for rayon repair *and* recipes for
preparing cat!
I'll make a full report if I discover anything helpful about the rayon
thing. Sometimes it "torques" out of alignment completely, but other
times it seems as if the sagging is relatively minor. Of course, I know
nothing about sewing so it might as well be brain surgery.
