Help dating embroidered peasant blouse

[DaisyandStella]

I have a couple peasant blouses and am having a hard time with dating. Any tips you could give would be greatly appreciated. Here's a couple pics of one of the blouses that I've photographed. The cotton is very thin / semi sheer and the blouse buttons up the back with a draw string tie at the top back to cinch. It appears to be an older blouse, but I'm unsure how to date these. Thank you in advance for your help!

From the fitted waist and button up back I would put this at late 1950's to early 60's.
