Please help dating this dress :)

Excuse the low quality photos :P

I found this dress at a thrift shop and to me it seems almost like a 60's dress (polyester, handmade with a metal zipper) but the material seems so pristine I wasn't sure if it was a reproduction. I would greatly appreciate your help!

Thank you.

Looks late 60s to me.

I see 60s too. It looks great on you! I love the pop of color.
