Melbourne shopping

I went to Melbourne today and did a little bit of shopping in the city. Well, when I say shopping I just go to look at things. I went to the GPO which is one of my favourite (and I think underrated) places. Up the top corner of the building is the Akira shop, who is one of my favourite designers. I was there with my sister and I pointed out a dress I thought was v nice and she agreed. When we left the shop, she told me it was $1500. I looked at most of the other prices (as I always do), but did not see this one.
I have been wondering over the price of things lately. I remember doing a fashion range when I was at college and we had someone come in and talk to us about pricing. In my collection, I had some lovely printed silk, which my Mum had bought when overseas, so I guessed the price to be about $45 a metre. Also in the collection, I had some cotton voile, which I bought for $2 a metre. I asked how I would price the garments given the huge difference in fabric price and that the garments were part of the same collection. I do not think I got an answer, just a look around the room for another question.
More of this at another time.
