Marshall Fields is a long standing Chicago Tradition. Their mall stores always carry tons of great clothing. They don't carry the most exclusive designer clothing, but very close to it. I have always found their customer service to be super accomodating. We used their wedding registry and were quite pleased with the online registry.
If you want a real treat, head to their flagship store in downtown Chicago. 9 wonderful floors of merchandise for browsing. I highly recommend taking a fanciful tour of the furs department. You can also find some really nice home furniture and decor items. And have lunch at the cafe - it's a nice break from all that shopping.
