I don't really care; people should wear whatever they feel comfortable in. In my opinion there is no such things as too old, too fat, too skinny, too short, too long, etc. People, especially us woman, are so preoccupied with what other people think of us. Should we wear this or that, or not? What matters is that you like how you look in a certain type of clothing, and that it feels comfortable. Jeans are also a kind of clothing that are very general, and there are so many different fits and styles, that I guess jeans are for all ages and body types no matter how you look at it.
