If you are in Melbourne, do pop up to the second floor of the Ian Potter Centre at Federation Square to see the exhibition Australian Made: 100 Years of Fashion. It's quite small, but there are some lovely pieces, and best of all, it's free!
My personal favourite is this beautiful 50's cocktail dress. It was made by a local dressmaker from fabric brought from overseas, which is embroidered all over in a lily-of-the-valley design in wool.
The clothing dates from the Victorian era to the 1960s (all women's wear, sorry gentlemen), and there are some accessories too, including hats, shoes and gloves.
These shoes really have to be seen to be believed, they are so incredibly narrow. I can't even visualise the foot that would fit into them.
