1940s

There have been many things on my mind lately, and I've been storing them up in the 'to blog about' section of my brain. But of course the thing that trumps them all is: fashion.

Here is my dilemma: I have a 1940s themed party to go to this Saturday. While I know very well what they were, I'm stuck as where to start when wanting to dress myself this way.

Does anyone have any tips on how to adapt current fashions to looks 1940s-esque? Or what to look for in op-shops? Preferably what's available in Australia too.

Thanks in advance for your help :D
