After anchoring retail in the City Market for the past decade, So Young's expanded into a larger storefront this year, establishing itself as a mecca for products central to our quest for metropolitan identity: cool, KC-branded souvenirs. Digital graphic artist Tony Choi has created a line of T-shirts, spaghetti-strap tops, trucker caps and wife beaters that are simple but sweet, emblazoned with Kansas City across the front. (His various fonts include one that's comic-book blocky and a gangsta-rific old English.) Choi can put just about anything on a T-shirt for less than 20 bucks, but it's his KC logos that have generated street buzz.
