Australian pieces to date

Hello, new here and excited about this awesome resource!

I have two dresses that I would like help with dating please. Both dresses were bought in Australia, but the seller knows nothing about them.

The Jacqueline Original is pure wool, A line, orange and brown checks, a small bow at the neck, and has a belt with plastic on the back.
The Crimplene is brown and black, hourglass shaped dress with a paisley type pattern.

Neither dress has any other tags. The Jacqueline Original 'wool' tag does not have the woolmark symbol on it.

Thank you for your help.
Alice

 

ditto - that mid decade period when its morphing into Mod c. 1963-64

 

Thank you! I definitely suspected 1960s for the woolen one just because of the colours, but the plastic belt's condition threw me. Good to know that they are both the same age.

 

Thank you, they really are so cute! And thank you for the dating as well.

 

Thank you! And thank you for the more specific date as well. I really did think 60s for the woolen once, and before 1964 as there was no wool mark. But the plastic belt threw me right off. I really appreciate knowing the most specific date too
