Vanity sizing: is it for real or a myth?

Of course vanity sizing is real. Women's sizes have been getting bigger over the last few years. What was a 12 is now an 8, and so on. Go to a good boutique and try on a wedding dress in your size. Ironically, wedding dresses are one of the few places where size inflation has not run rampant, though you think that would be the place where it would be the worst.
