The best Oscar outfits ever worn on the red carpet

Sometimes simplicity is key, and we're very into this Calvin Klein sheath dress worn by Saoirse Ronan. The matching shoes are the icing on the cake.

This dress makes us think of fairies and happiness.

Not everyone was feeling this floaty, scarf-inspired gown that Scarlett belted with a studded black number.

Emma won an Oscar for La La Land, and won our hearts with this Givenchy Haute Couture dress. OBSESSED.

In 2016 we almost let Kate Winslet off her dress because she arrived arm in arm with Leo.

This yellow number from Jennifer Hudson is so complementary. Simple yet stylish, we are a big fan of Jen's 2015 Oscars look.

We love you Cameron, we do. But not everyone was feeling your 1998 look.

Margot Robbie dressed like an Oscar for the 2016 awards and we love every inch of it.

We can always rely on Lady Gaga to bring the drama, and that she did with these red leather gloves.

No words.

This pretty princess look made Lupita Nyong'o one of the best dressed on the 2014 red carpet.

So what? She tripped up the stairs, we'd give anything to wear J-Law's Dior gown from the 2013 Oscars.

This dress is like a work of actual art.

Naomi Watts has most definitely learned from her fashion mistakes since this 2006 look.

Mila Kunis wore this lavender number to the 2011 awards.

Charlize is an Oscars red carpet icon so this 2010 look was a bit out of the ordinary.

Anne's dreamy dress by Armani Privé worked because it was unfussy but fabulous, ticking all the Oscars boxes. More please!

Dressing a baby bump can be tricky at the best of times (let alone at the Oscars!) but in '08 Jess did a masterclass in maternity wear with the help of Marchesa.
