downtown naperville like everyone said is your best best..also if your lookin for somethign else to do like during the day
theres oak brook mall like 15miles up I88 east towards chicago...oak brook as an outdoor mall but one of the more upscale malls in the the state..its got the nordstoms and neiman marcus and all the main stores that are at the outlet mall like they got a Louie V and bcbg and tiffanys, really everything you can think of..basically its like hittin up michigan ave downtown but not having to deal with the tourists and the no parking and everythign else..not to mention great food places like maggianaos and cheesecake factory among other real nice restuants
then about 10miles west on I88 there is the Premium Outlet malls and if you have ever been to the ones in orlando florida its liket he same with like... Ann Taylor, Banana Republic, Calvin Klein, Coach, Elie Tahari, Gap Outlet, Giorgio Armani, J.Crew, Kenneth Cole, Lacoste, Nike, Polo Ralph Lauren, Salvatore Ferragamo, Sony, Theory, Vera Bradley and like 100 other stores
too bad you didnt make the trip before christmas, then again maybe its better cause you dont have to buy anything for anyone but yourself
