Flowers
The flowers that Jasmine looks at are symbolic of her rebirth into a radically different life.
Jasmine's Clothes

Society
On its surface, Blue Jasmine is a film about a woman who must adapt to her new life circumstances. However, on a deeper level, the film is an allegory for the way that society ignores things that make it uncomfortable - even if the thing it ignores is important.
Jasmine's Husband
Jasmine's husband is symbolic of American businessmen greed and malevolence - particularly people like Bernie Madoff, who like Jasmine's husband went to prison for fraud.
Mental Illness
Mental illness and its effects is a frequent motif in Blue Jasmine. The film begins with the aftereffects of a severe nervous breakdown. Throughout the film, viewers see Jasmine abuse alcohol and anti-anxiety medications because of her mental illness.
