Václav Brožík: Sleeping Governess. Undated.
This is a weird picture. It seems like a costume - not 19th century!
Vojtěch Hynais: Lady with Violets. Ca 1896.
Hynais: Lady with a Fan. 1891.
Hynais: Lady in a Pink Dress. 1880.
I've discovered this painting thanks to the Dreamstress's Rate the Dress. Amelie Auguste is the only one so far who rated 10/10. It's now my Favourite Dress Ever.
