We will be providing an update when we have more information on the first day of the sale. (One immediate question is, of course, there are actually 4 days from 9 to 13 October...)
In the meantime, do go take a look at the AP website and visit their retails shops at Lane Crawford IFC and Canton Road to try out the sizes. Goodies do get snatched up REALLY quickly once the sale starts in UK time, and the website always gets very busy. One of the things to keep an eye on are the corsets, which usually cost a fortune but can sometimes carry a huge discount.
