Tresor is the German word for safe or vault. It's an underground techno club in Berlin, but also a town in the Democratic Republic of the Congo. In French it means treasure, while in Fiore-speak it's the name given to classic 40 denier opaque stockings with a dramatic sparkly bow that gift-wraps your upper thighs. A great choice for the party season, especially on a chilly day. Invisibly-reinforced toes.
