The portrayal of Ophelia

In hamlet we know that Ophelia had recently suffered loss and was struggling emotionally this led us to the scene were she is singing and isn't quite there entirely. Because of the paintings I constantly pictured her as a neat elegantly dressedn woman 24/7 but through out the various adaptations I have scen, I was certainly headed in a different direction. What do you think?
