Emma Watson started off her week wearing a Proenza Shouler dress at a London photocall. She kept her make-up to a minimum and completed her look with Giuseppe Zanotti platform gladiator sandals.

For the London premiere of the movie, the young actress chose a beautiful vintage Ossie Clark printed gown.

Then Emma flew to New York to promote Harry Potter and the Half-Blood Prince. She went on The Late Show With David Letterman wearing a nude Christopher Kane Fall 2009 dress. She paired her outfit with a black clutch and gold Charlotte Olympia platforms.

For the New York debut of the movie, Emma opted for the Proenza Schouler dress again. She daringly combined it with an edgy leather number.

For an appearance at “The Early Show” Emma Watson donned a silk red Saloni Alexia dress and Chanel Resort 2009 cage ankle boots.
