The largest shopping opportunity near Pearl Harbor is the Stadium Flea Market - open in the morning on Wed, Sat, Sunday. It is just down and across the street from the Arizon. Depending on the sort of shopping that interests your wife this may suit her. It is a good place to buy t-shirts, souviners, etc. (This isn't a flea market with used stuff or a garage sale section - just vendors with new merchandise). Otherwise Ala Moana would be the next best choice. Pearl Ridge is a much smaller mall - although there are a few unique shops with Hawaiian crafts. Pearlridge is a small mall - Macy's at one side, Sears at the other (JC Penny just closed) otherwise mostly the usual mall type stores (Gap, See's chocolates, Kay Jewelers, etc.)
