From the term quaint. Historically in the 1810s, females with dandy attributes were called dandyess or dandizettes. As dandy became a descriptor applied exclusively to men starting in the latter half of the 19th century, quaintrelle then became the word applied to females.
quaintrelle (plural quaintrelles)
- (obscure) A woman who emphasizes a life of passion expressed through personal style, leisurely pastimes, charm, and cultivation of life’s pleasures.
