The lingerie industry has expanded in the 21st century with designs that double as outerwear. The French refer to this as 'dessous-dessus' which basically means innerwear as outerwear. The boutique Faire Frou Frou, which is an antiquated phrase meaning "show it off", heralds this philosophy by categorizing lingerie as an accessory with details such as straps and lace trim that should be layered and shown as part of one's outerwear.
