Yes, to preserve the egos of an increasingly heavy costumer base. In addition, sizes are not consistent in the fashion industry; I have a closet full of clothes from size 6 to 10.
Anyone who sews clothing is very aware of the size inflation. Patterns have used the same sizing standard for generations. So, while I purchases clothes of sizes 6 to 10, I have to make clothes of size 14 to fit.
So, todays size 8 is roughly the 1950s size 14 (Marilyns size).
Is todays size 12 like 1950s size 18?
And why...why do fat women think that showing off their card-hiding fat folds is attractive? (All I can think of is the bacteria partying in there.)
