Julianne Moore
While the Still Alice actress has been wearing a lot of Givenchy recently we think she could make a surprising designer choice (like, say, Elie Saab) for her big night.
Reese Witherspoon
The Wild star has been playing it safe in 2015 thus far, but we're hoping that's because she's been saving the high drama for Sunday night. Sure, Reese could bring it in a bold color or she could take things to another level with this Stephane Rolland dress.
Sienna Miller
This Valentino dress was made for the Oscars red carpet. And while a lot of gals could pull it off, we think the American Sniper actress—with her signature boho flair—would be the perfect fit.
Lupita Nyong'o
We've seen the Oscar winner wow in every color of the rainbow but she has yet to have a major pink moment. Here's hoping it finally happens in this Georges Hobeika gown.
Felicity Jones
We really really want the Theory of Everything star to have a Cinderella moment at the 2015 Oscars and this Carolina Herrera gown would totally do the trick. No glass slippers needed!
Chrissy Teigen
We have a feeling John Legend's wife will go for glitz and glamour on Sunday and there's no better designer to do so in than Zuhair Murad.
Rosamund Pike
The Gone Girl star likes to take chances on the red carpet and this Ralph & Russo confection is the perfect way for her to indulge her adventurous side and make a serious style statement.
Jennifer Aniston
A no brainer! This Valentino dress is also known as a Jennifer Aniston special.
Cate Blanchett
We already know this color and silhouette work on the Oscar winner, so would it really be a surprise if Cate goes with a near repeat from Giambattista Valli?
Naomi Watts
Watts like simple styles and lots of sparkle—and hey, what do you know? This Armani Privé gown is both of those things.
Emma Stone
The Birdman actress has been doing the menswear effect all awards season long, but we think she'll break that streak at the Academy Awards with a modern princess look—like this Valentino gown.
Keira Knightley
Like, no duh, the Imitation Game actress will attend the 2015 Oscars in Chanel. And if the expecting star doesn't go with a custom look (she'll probably go with a custom look) then maybe it will be this number from Karl Lagerfeld's most recent couture show.
