Ha, that article is spot on. I hate the fact that I ALWAYS have to try on everything because I cannot rely at all on the size on the labels. I wish there was a universal sizing system. I wouldn't care what size I ended up being, as long as I knew that I could buy that size in any shop and it would always fit.
I have clothes in my wardrobe that are all the same size (because they all fit me!), and yet the labels range from a 10 to an 18!
