A number of the antique dealers in the Spokane/Couer d'Alene area have antique clothing displayed for sale. I don't know how well it sells and off hand don't remember price ranges either.
I have clothes of mine from the very early 70's in excellent shape and haven't figured out what to do with them either. I tried our yard sale, but the girls that were interested couldn't fit into them. I used to be a skinny little thing (sigh).
