1950's or 1960's Pariser Chic dress?

[Arabella's Treasures]

I am dilly dallying between late 50's and early 60's with this feels like silk dress by Pariser Chic. The hem falls below the knee and it has a central back zip. Can anyone else advise?

It looks 50s to me, actually reminds me a lot of some of my grandmother's dresses from that time.

Another vote for '50s - lovely print.
