It's curtains for you

A friend of mine was de-stashing and she gave me mountains of old curtains in a splendid 1970s floral. So I made a shirtdress from 1967 pattern Style 1542 and I reckon it's a corker! The heavier-weight cotton twill and awesome 3/4 circle skirt is fantastically swingy. Hooray for benevolent friends!
I think I'm going to cheat and make it up again in a 1950s fabric, soften the collar a little, and wear it to the Fifties Fair. You think I'll get away with it? Or will I be set upon by militant vintage types?
