The biggest night in Hollywood fashion did not fail to deliver breathtaking fashion or unfortunately dull looks.  

Not a lot of mistakes were made this year on the Academy Award red carpet which aired on Sunday, Feb. 26, 2017.

A hot commodity on the red carpet were the gold dresses. Non-nominees like Jessica Biel and Blanca Blanco also wore the color of the good ol' Oscar - vibrant gold. Thankfully, they have no chances of jinxing a win.   

Justin Timberlake is incredibly proud to have his gorgeous wife, Jessica Biel, by his side at the 2017 Oscars. The famous couple stopped by E!'s Live From the Red Carpet and chatted with Ryan Seacrest about the exciting evening—starting, of course, with actress' stunning Kaufman Franco ensemble and Tiffany jewelry.

Fashion Archive: The dress worn by every best actress winner

We saw a lot of form fitting and slimming gowns worn by the most beautiful and talented actresses. There are too many winners to count. But we are partial to Hailee Steinfeld's flowy and ethereal gown. 

As far as disappointments, actresses like Charlize Theron and Scarlett Johansson seemed to take a backseat on the fashion train. 

Take a look at the gallery above for the best and worst dressed at the 89th Academy Awards.
