 According to the directors commentary, William H. Macy (qv) was  given three suits to wear during the film. During scenes where his  character Bernie was hapless and unlucky, he wore a suit that was  two sizes too big for him. During scenes where his luck was starting  to turn around, he wore a suit that was one size too big for him.  After he falls in love and is extremely lucky, he wears a perfectly  tailored suit. Also, as Bernies luck improves, the lighting  surrounding him gets brighter, and his shirt and tie go from dark  and subdued to bright and colorful.
