Stylish Bag Carriers

What do you do with that book, those papers, that calculator, must read magazine? You are on the subway, meeting friends for dinner, going to some private lesson, on your way to the movies or a meeting, what do you use to carry those things that you need to have with you? In America you pull out a backpack or a big shoulder bag...in Korea they put it all in shopping bags advertising Ralph Lauren, Hilfiger, Gucci, Bean Pole..did they actually get the bag while shopping at these ultra shi shi places...most probably are knock offs...who knows but I tell you it sure does look more stylish to carry a paper bag with the name of an expensive brand name than a backpack.
