Women are no longer the weight and height of pre war 2. Women are now bigger in size and have greater earning capacity. Iconic would be missing an opportunity to make more sale if they did NOT provide the sizes that women are today. A Global sizing should exist in the same manner e.g. Size 2 = size 10 elsewhere. We need to know where the garment is made to hazard a guess to its legitimate size e.g. US sizing is small compared to English. There are many designers that for some reason they don't make in AU 16, 18, 20. These are the sizes that as women get older need, the working woman has discretionary cash to buy items in these size ranges. I reiterate, you are missing an opportunity to make greater sales and meet market demand. 90% of styles would look as good on a 16 - 20, predominantly women of today dress in the style of the day. They know what suits them and what doesn't. Let them be the deciders of what they have a choice in buying. Whomever decides weights and measurements Globally should take steps to bring all cuts into line. Thus eliminating and managing the return of garments. A cost saving to the Seller and greater confidence in the sizes chosen.
