Thought of the Day - Pants: Men vs Women

Today at work we were discussing men's vs women's pants and why they are not the same. Women's sizes vary from store to store while men's sizes are the same everywhere you go. Also, why do men get to have 2 sizes (the length and the width) when women only have 1? If anything, women should need the more exact sizing since their pants fit much differently than men's. It is also makes it much easier for women to buy men their pants then, since you can go to any store and know what size they are. Men don't have it that easy at all if they wanted to buy their girl a nice pair of pants. Why can't they standardize this for men and women?
