Marilyn Monroe's sexy white halter neck outfit has been voted the most iconic movie dress of all time. The frock, which famously flew up as Marilyn stood on a subway vent in 'The Seven Year Itch', was playfull but pure.

The poll was conducted by Miss Butterfly. A spokesman from the site said: "Marylyn Monroe's white halterneck dress is truly iconic and is instantly recognisable worldwide. It goes to show what a powerful medium film is for fashion and actresses are often defined by what they wear."
