how has fashion in 1950 impacted on shaping the australian identity
Since this is not my area of expertise, I searched Google under the key words "1950 fashion Australian identity" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
