Fashion was almost completely uniform by the time Queen Victoria ascended the throne in 1837 and it was essentially homogeneous when Edward VII became King in 1901. But this is 1683 and Eva Thokoly's dress has a Hungarian laced bodice and rounded basque. The sleeves could be imported from a Beaubrun brothers portrait, but the lace-edged apron is Hungarian. To see this style brought a few centuries more up-to-date, see this collection of portraits of Elizabeth (Sisi) as Queen of Hungary in Hungarian dress. Also see this portrait of Empress Maria Theresia wearing Hungarian dress.
