Dating silk slip dresses

Hi everyone, I'm wondering what era these slip dresses are from. I couldn't find this exact Lady Lynne label and the other has no label except for a size tag. The unlabeled one feels like pure silk. Can anyone help tell when these are from?

Look like 1940s and so fabulous. Lady Lynnes are great slips. You can google Lady Lynne lingerie and learn more about them. Very popular in the 40s and 50s.
