The quality of being featurely; the state of having well-formed or attractive features.
From featurely (an archaic adjective meaning 'well-formed' or 'shapely') plus -ness, though this is an extremely rare word formed in the older English tradition of describing physical grace.
This word is so archaic it's practically extinct, but it shows how English once had many more words to describe physical beauty and grace—older poetry valued featureliness as a sign of nobility or virtue.
