An anthropological literary suggests that Circassians were best characterized by what was called "rosy pale" or "translucent white skin". While most Circassian tribes were famous for abundance of fair or dark blond and red hair combined with greyish-blue or green eyes, many also had the pairing of very dark hair with very light complexions, a typical feature of Peoples of the Caucasus. Many of the Circassian women in the Ottoman harem were described as having "green eyes and long, dark blond hair, pale skin of translucent white colour, thin waist, slender body structure, and very good-looking hands and feet". The fact that Circassian women were traditionally encouraged to wear corsets in order to keep their posture straight might have shaped their wasp waist as a result. In the late 18th century, it was claimed by Western European couturiers that "the Circassian Corset is the only one which displays, without indelicacy, the shape of the bosom to the greatest possible advantage; gives a width to the chest which is equally conducive to health and elegance of appearance".
