Recently I asked one of the owners of Bluebird Boutique how she felt about the arrival of Bumbershute, which could be perceived as competition for the designer dollar. "Great," she said, and I'm inclined to believe her logic - "now her Wayzata customers have reason to shop at 50th and France. The more the merrier." Indeed, power in numbers was on the mind of Bumbershute owner Kathryn Paulsrud when she made the big move. She figured 50th is more of a regional draw. And becoming more so every day. Nani Nalu made the move from Ridgedale Center to 50th. Priscilla of Boston, like Monique Lhuillier, picked it for its first Twin Cities store. And the latest announcement: St. Paul destination boutique Stephanie's will open a second store at 50th in August - the same month the Bluebird girls will debut their accessories store, Ladyslipper Boutique. 50th has always been a distinguished address, but lately, there's an undeniable energy as the shopping district proves itself to be the destination for boutique shopping in the Twin Cities with a well rounded mix of styles and price points (plus great places to eat and drink). If you want to impress your out-of-town fashionista friends, there's no question where to take them.
