50s or 60s

Most people assume the 60s fashion to be either hippie (which is mainly a 70s fashion movement)

or Mod (which was more underground, and popular with youth culture)

Most women were still wearing pretty dresses, well constructed with tulle skirt and a collared shirt. Madmen is very accurate when depicting 60s fashion.

Betty Draper, far left is probably the most accurate of the average woman. I think it would be best to go with an early 60s theme or late 50s theme. This was before clothing was majorly outsourced, so there is true craftsmenship.
