Add to the whole issue of what's a normal size, the fact that clothing manufacturers are steadily making clothes BIGGER. Even the very small sizes are not what they use to be.
In High school, I was size 5/7 and that was very small and what they considered a junior size. Now a hundred years later, lol, I'm miraculously a size 0/2! I'm not any heavier now and in better shape. So I see no reason why according to the sizing they use now, I shrunk!! I still have my favorite pair of jeans and they fit really nicely still.
In an effort to make a heavier and heavier female population feel "happy", they are punking us. A size 14 now which is the supposed average was probably a 16 /18 years ago. 4951
