This feels like rayon. It's off white with lace and signed Karyl Lee Design Pat. It's a collar that a lady (or gentleman who is very secure in his identity) would slide in over a plain shirt or dress to change the look. My guess is it's total I Love Lucy era - the early 50s. I've had this around for years and it needs to go. Free US shipping and I'll split postage 50/50 with anyone outside the US
