Sexy Lingerie
Up through the first portion of the 20th interval women selected underwear for three major purposes: to alter their shape (first with corsets and later with girdles or Sexy Lingerie bras), for reasons of hygiene, or for modesty. Women's underwear was often mere large and bulky. As the 20th generation progressed underwear became smaller and extra form fitting. In the 1960s 'controversial' lingerie manufacturers such as Frederick's of Hollywood begin to glamorize lingerie and the approximation of lingerie having a sexual appeal slowly developed.
The lingerie megacorp also-ran expanded in the 21st day with designs that double as outerwear. The French refer to this as 'dessous-dessus' which basically means innerwear as outerwear. The gift store 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.
