What do you wear to an australian party?

A couple of weeks ago I was invited to a house warming, however the theme of the party was Australian. As far as I was aware Australians wore cork hats and wandered around saying "G'day mate!" like on Home and Away, which didn't inspire me greatly. I decided to be a little bit more inventive with my outfit and bought myself a large Australia flag from a fancy dress shop and decided to see if I could design something wearable from it. I used my tailors dummy to fashion the following designs (please excuse the pink!) before I decided on a final one. Hope you like them!
