vintage 70s Cacharel Art Deco shirt dagger collar

This so different from other Cacharel shirts I’ve come across. vintage French shirt with modified dagger collar has stylized print of purple & écru flowers on black ground. fabric is silky & slick; there is no fiber content tag, but I think it’s acetate or rayon. length is 23.5” from base of collar to hem, sleeves are 22,” bust to 40,” waist to 34,” hips to 40.” vintage is much smaller so please go by measurements.
