So... basic marketing/visual merchandizing. Presentation is important.
There's a famous story in the retail world about a dude and his wife that bought a couple hundred shits over seas for dirt cheap and thought they could sell them at flee market for some quick cah. They set up a booth and tried to sell the shirts for $5 each. Nothing sold. The next week they bought a $50 mannequin bust form, put a shirt on it and charged $10. They sold out. They turned into some big clothing line but I forget what it was.
