Michelle was the heavy favorite among E! Style Collective members.
"Best Oscars hair in history is Michelle Williams in 2006," noted hairstylist Jennifer J. "It was old Hollywood glamour in the most beautiful golden tone, but it still had a bit of a messiness to it, a little undone."
"[Michelle] was swoon worthy in an effortless, side chignon," added style blogger Nashelly Messina. "It was polished, yet undone, and looking back, timeless."
"I loved the feminine yet cool shape to the hair, and the lovely yellow dress red lip combo...so fresh," concluded celebrity makeup artist Tina Turnbow.
"Sarah Jessica Parker at the 2010 Oscars had a beautiful up-do," noted celebrity hairstylist Kim Kimble. "It was a risky choice but fashion-forward and appropriate for the dress and occasion. She's one of my favorites; her curls at the 2009 Oscars were also on point."
Jennifer's hair is pretty much always perfect. So when deciding between the year she took home an Oscar with her sophisticated updo and this 2013 look, we opted for the latter. Her fringe paired with long, super-straight locks was refreshing in a sea of chignons and retro waves.
The typically blond bombshell shocked viewers when she showed up at the 2014 Oscars with brunette locks and mauve-plum lips.
"I loved this style because it was sophisticated enough without looking dated," said makeup artist Ashely Rebecca. "It was the perfect blend of an updo style and natural look, executed perfectly. Kate's 2009 hair looked elegant, and it was different enough than normal waves or chignon buns that it stood out."
Braids may be on-trend now, but Jen first did it way back in 2009.
Anytime you wear a seemingly casual look like braids to a mega-glam event like the 2008 Oscars and still look like a million bucks...well, you'll always be a winner in our book.
"It's just a classic look," said makeup artist Karen Sarahi Gonzalez about the Wild star's 2013 locks. "I feel like it can go all year round, and it can fit any occasion whether it's red carpet or a party. It's just one of those that never goes out of style."
"I love the texture with the frizziness but also the updated French twist," said Whitney Port about Amanda's 2013 Oscars 'do. "It was a perfect mix of done yet undone."
