I must admit, I didn't expect the crowd. OPM, the new designer boutique at Excelsior & Grand in St. Louis Park, packed the house for its grand opening fashion show on Friday night. The young and fabulous were out in full force, noshing on pink frosted cupcakes, sipping cocktails and drooling over the endless parade of designer bags. A darling Catherine Malandrino black cocktail dress with white stitched details was my favorite, and actually surprised me by being only $500. There were a couple of other noteworthy party dresses and a great sweater or two, as well as whole bunch of skinny pants and slinky tops. I've been wondering if this store will catch on, situated as it is, at the back of the Excelsior & Grand development, which hasn't turned out to be a hot spot for retailers, and with its luxury price points in this economy. But, if the crowd that attended the show can afford to shop the store, they just might make it. In any event, it was an auspicious start - I applaud OPM for pulling out all the stops and throwing a fab, free party. We can all use more of those.
