These look to me to be most likely from the sixties, if not then more likely older than newer. Picked up a stain somewhere along with a few very small ones, it goes through to the back a little bit also, should not be any great trouble to get out but I am leaving it as is. Bright white shade. Yes you need vintage skivvies for either reenactment or mannequin uniform display, they look only slightly less stupid with the fly open and no undies. Also required for retro "USO" style shows so you can do the bit where you "accidentally" knock down the folding screen while changing.
