Judging by the sheer number of Audrey Hepburn short hair looks that exist, it's clear why the late actress is one of the most enduring style icons of all time. She rocked pixie cuts and swinging '60's 'dos with equal panache. Below, we take a look at some Hepburn's most iconic hair moments.

Roman Holiday
"Roman Holiday" propelled Hepburn into international stardom. In the film, the actress, who plays a princess, escapes the confines of her castle and spends a memorable day in Rome with a reporter played by Gregory Peck. One of the first things she does is get a haircut, resulting in an Audrey Hepburn's short hair look that has been copied by many women. This pixie cut combines closely cropped bangs with cute curls, and the result is tres chic.

Sabrina
Hepburn won an Oscar for her role in "Roman Holiday". She immediately followed this star-making movie with "Sabrina," the 1954 film where she plays a chauffeur's daughter who is wooed by a pair of rich brothers played by William Holden and Humphrey Bogart. Hepburn's character gets a makeover on a trip to Paris, and she trades in her teenage ponytail for a sleek, short 'do. Audrey Hepburn's short hair in "Sabrina" is similar to her look in "Roman Holiday", but the styling makes her pixie cut even chicer. While her "Roman Holiday" locks were worn in carefree curls, her hair is slicked back in "Sabrina". Her short bangs are carefully arranged, and the sides are pulled back to create a faux updo effect.

How to Steal a Million
While "Roman Holiday" and "Sabrina" exemplify Hepburn's '50's styles, in "How to Steal a Million", the star starts to adopt a '60's aesthetic. In this film, the actress plays the daughter of a wealthy Frenchman. When she needs to pull off an art heist, she enlists the help of master thief Peter O'Toole. In the movie, Audrey Hepburn's short hair features long bangs, sideburns and volume at the crown. This cut was created by famed stylist Alexandre de Paris, who dubbed it the "Coupe Infante '66."

Two for the Road
In the 1967 film "Two for the Road", Hepburn wore a similar short hairstyle. The movie chronicles her character's rocky romance with Albert Finney, and it flashes between their early love story and current marriage. In the late '60's portion of the film, Hepburn dons a number of fashion-forward ensembles, ranging from a funky trouser suit made from PVC to a Mary Quant minidress. Her hair is well suited to these outfits, and the cut was inspired by the Vidal Sassoon five-point style. It is notable for the W-shape at the nape of the neck and the spike of hair at each ear.
