They are comfortable.
Comfortable, cheap clothes, same as americans and their love of hoodies I guess. In europe they are still poor peoples clothes, if you have any money at all you don't wear them as day clothes.
They can get fat without buying new clothes.
generally you will find that the majority of people in eastern europe are the opposite of fat and obesity is quite rare. their is more pride in the body but less in the fashion in some areas and sports wear is still seen as cool or tough in their eyes.
Really? They do?
it is true, i know from experience and can vouch for mistermanners. even when they move to other countries you will find most keep a tracksuit in their wardrobe. it is a male thing though and women are much more fashionable.
