If you're wanting to buy designer handbags, shoes and jewellry in Australia, Cultstatus is probably your best bet. They stock brands like Balenciaga, Proenza Schouler, YSL, Givenchy, Alexander McQueen, Lanvin, Alexander Wang, etc.
You can only order by email, so customer service was very personal and helpful. After a few emails and sorting out my payment, i received my Balenciaga bag the next day by courier. While i've had an excellent experience with Cultstatus, i would not order from them again, as purchasing designer goods in Australia is just way too expensive. I saw the exact same Balenciaga bag in Germany for 700 Euros cheaper than what i paid at Cultstatus.
