I just found a cute little boutique in Central that sells a gorgeous range of evening dresses from mid range designers Of course the original labels are cut but the cut and quality are the same as the ones sold at US department stores.
Prices start from a very reasonable HK$1500. If you do not fit the size that is in stock the shop will order your size which will take around 1 week. Sizes range from US 0 to 8.
