<p>A general suggestion for finding stores (not just in Chicago) : google Prom Dresses 2008. You can browse through these websites - you’ll see a lot of the same brands keep coming up ( with wide ranges of prices and styles within each line). Then do a search on the manufacturer’s websites for local stores near you. You’ll find a lot of the nice boutiques using this strategy. If there’s a store that carries several lines, it’s a good bet for a trip.</p>
