Your probably didn't know that Chelsea Clinton is 5'9" tall. You probably didn't know that because Chelsea Clinton rarely gets noticed apart from her parents. You can't really blame her for choosing to fade into the background - growing up in the limelight and being constantly critiqued on her looks couldn't have been easy. Even while helping her mother campaign for the Presidency in 2008, Chelsea chose clothing that was generally safe and boring rather than flattering. Neutral colors, boxy shapes and dowdy blazers summarize her wardrobe, which is really too bad because she's clearly a lovely lady.
