Actually I think the whole "baggy" trend (starting with baggy jeans in the 90's, baggy down jackets later, and now this) was due to people trying to look like they can't afford clothes that fit them, so they wear hand-me-downs or Goodwill stuff.
Serious, most American kids like to look and act lower-class than they really are. It's a self-esteem thing. They don't want to look like nice suburban kids, because that's too boring in their opinion. It's the same reason most kids hide how smart they are. They don't want to be dorks. They'd rather sit in the back of the class with the "cool" kids.
The trendy/urban city people who wear those quilted puffed down jackets? See, it's like this: Those jackets used to be exclusive to rural areas......redneck country boys, hunters, ranchers etc....... because they're cheap yet effective against the cold. 30 years ago, upper-class people wanted nothing to do with them. The only reason those jackets started being seen in big cities is because winos & skells received them as a donation from the homeless shelter, or dug it out of a garbage can. And then rappers started wearing them, to try and look like they stay close to their ghetto roots. And then all the well-to-do suburbanites and trendy Hollywood types start wearing them too, because they are self-conscious about their wealth, and want to look like they're "down with the stuggle".
