I've been lucky to have several people gift me lace collars. Each has some minor condition issues, that I will "fix" if I can. Basically securing loose stitching if I can do it so that it's not really noticable!
I don't know how period they are..although in some of my research lace collars seems to be early..but then again, I do fit the age range where I can wear old stuff..lol!
