Gentlemen Prefer Blondes

Gentlemen Prefer Blondes is a 1925 comic novel by Anita Loos, following a gold-digging flapper named Lorelei Lee.

The phrase became iconic through its 1953 film adaptation starring Marilyn Monroe, cementing the cultural stereotype that men favor blonde women.

The title is often invoked ironically or as shorthand for this supposed preference: She dyed her hair, figuring gentlemen prefer blondes.
