Throughout the entire movie, the female lead wore the exact same overalls, whenever she came from her studio, or was working in her studio. It is obvious because the paint splatters are in the exact same place on her clothes. As a professional artist, and a busy one, there is no possible way that she does not own more than one item of clothing that she uses to paint in. This movie takes place over multiple days, and it's impossible to imagine what the smell would be like if she wore the same thing daily, especially out in public.
