So I think I saw this film about 10 years ago on tv. From what I remember it starts with a man recognizing a painting in a shop window and after inquiring finds out the the artist is dead. He then discovers that he had a daughter with the artist who is being raised by her sister. I think the daughter and the aunt then go and live with him. One scene I do remember is that the father invites the aunt to an all black party and she shows up wearing a red dress. I think they get together at the end of the film but that’s just a guess. I think it could possible be a made for tv film from the 90s.
