Actress Emma Watson wears a leather (or pleather?) halter top at the New York Premiere of her film Harry Potter And The Half-Blood Prince. This was at the Ziegfeld Theatre in New York City on July 9, 2009. This was the sixth of the eight movies in the Harry Potter franchise, with Emma Watson playing Hermione Granger, who (per Wikipedia) "often uses her quick wit, deft recall, and encyclopedic knowledge to lend aid in dire situations." Emma Watson was born in 1990, so she turned 19 the year this photo was taken.
