From what I have heard if you are after suits made by Gucci,D&G, Prada etc I think you should wait until you travel to New York and have a look around there. From all accounts I have heard you can buy a few suits over there and the savings covered as opposed to buying something of a similar caliber here in Australia nearly just about cover the flight. In saying that though I cannot talk from first hand experience as I have not been, but that is what I have heard from a number of people. Even if I am wrong no harm in waiting a couple of months surely:P. Also if you cannot wait try Hugo Boss store as said above or Pierucci, they do some nice suits.
