MIAMI mag and stylish denizens of Miami nightlife welcomed the new addidas Yohji Yamamato Y3 store to the Design District last weekend. The sneaks are uber-Tokyo-cool. The store is magnificently minimalist. And there's a fantastic second-floor gallery space with a projector and kitchen for special events. At the end of the night there was a mad rush for the gift bags which contained a swanky unisex bag. The Design District beat out South Beach once again.
