Julie Andrews Style Evolution: 'The Sound Of Music' Star Goes From Sassy Costumes To Prim Pantsuits (PHOTOS)

Whenever we watch Julie Andrews spin around the Austrian countryside and belt out "The Hills Are Alive" in the 1965 musical film "The Sound of Music," we can't help but be amazed by her pure talent. Yet, we can only imagine the moment Andrews' mother and stepfather (both Vaudeville performers) first heard her four-octave range -- signaling a lifelong career that has earned her an Academy Award, Golden Globe, Emmy, Grammy and Dame honor from Queen Elizabeth II herself. But beyond her impressive list of accolades is Andrews' family-friendly style transformation.

Experimenting with trends throughout the decades, from psychedelic '60s print dresses and '70s flare pants, the blonde beauty hit her ladylike stride in the 1980s when she'd appear on the red carpet alongside husband-director Blake Edwards sporting feminine pieces (with bold shoulders, of course). And the big screen legend continues to age gracefully with a pantsuit collection we'd argue could rival Hillary Clinton's.

In celebration of the real-life Mary Poppins' 77th birthday on Monday (October 1st), we're taking a look back at the star's style over the years. Vote on all her looks in the slideshow below.
