You Don't Want to Miss This Week's Red Carpet Hits

Updated on 11/16/2014 at 12:00 PM

From Rooney Mara in a sexy black Givenchy dress to Nicole Richie in her white H&M steal, this week's most stunning ensembles were lessons in going monochrome. Their high-impact looks, along with appearances from Kate Middleton in all-black DVF and Keira Knightley in white Chanel, might just convince you that less really is more, at least when it comes to the color wheel.

Of course, because we have a weakness for scene-stealing patterns, too, we had to include Shay Mitchell, who rocked a metallic Tory Burch number earlier in the week, and Poppy Delevingne, who showed us the key to toning down a loud dress is a casual pair of sneakers. Just scroll for a complete look at this week's red carpet hits ahead.

Keira Knightley

We're digging the jeweled details on Kiera's white Chanel dress, which looks like it was made for the actress.

Katie Holmes

The actress stepped out in a shiny LBD for an event at the St. Regis Hotel.

Jennifer Aniston

Thank you, Jennifer Aniston, for giving us a bit of work-appropriate-outfit inspiration with this Bouchra Jarrar top and black pencil skirt.

Poppy Delevingne

The model wore this patterned minidress to celebrate her new Solid & Striped collaboration.

Rooney showed us that ruling the red carpet is just in the Mara genes.

Nicole Richie

Current status: stalking the H&M website to see when they'll restock this body-con.

Yes — the Duchess of Cambridge's maternity style has been on point. This DVF gown looks flawless on her.
