The scene that I clearly remember is that the female lead (FL) and male lead (ML) are at the ML apartment and the FL sees his artworks and wants him to draw her too. He is reluctant to do so. So the FL decides to start taking her clothes off one by one. The ML see this and starts to reach over to his sketch pad. The more clothing she takes off the less reluctant the ML is of drawing her. I think it ends with the FL in her under ware and the ML lead sketches pictures of her. Another scene I remember but I am not so sure is that the FL and ML attend a party together and the FL is wearing a green color dress that is like knee length and is puffy on the bottom. Thank yo so much for your help.
Is it As Good as It Gets? There is a sketching scene between two characters, and the FL does wear a green dress at one point.
