Vernacular architecture: In a small way, Jaklitsch practices his own sort of vernacular architecture with the Marc Jacobs shops, most of which have been inserted into existing structures. He takes pains to make each store location-specific and to honor the site's original intent, whether it's an old tobacco warehouse in Savannah, Georgia, a shop in strip-mall-happy Los Angeles, or a renovation inside Paris's Palais de Royale.
