The classic white shirt is as key to American style as blue jeans.
It is chic and simple.
Practical and unpretentious.
It can be paired with jeans (Jackie O in Hyannis), black pants (Uma Thurman in Pulp Fiction), a long skirt (Audrey Hepburn in Roman Holiday), or a gown (Sharon Stone on the red carpet).
It is also useful for covering up a bad outfit when entering a good hotel (Julia Roberts in Pretty Woman)
