Rich people can afford to eat more and so require larger clothes.
This has been bothering me: actually it's the other way around, rich people are generally lighter because they eat better food. Poor people eat crap and get big and fat. They are also more likely to have sedentary lifestyles. Rich people have better education about health issues. They will also have the money to buy lower-fat or organic foods. Hull (poor) is the fattest place in Britain, Kingston (rich) is the skinniest.
