27 Raf Simons' Dior Greatest Hits, Because He Will Be Missed On The Red Carpet — PHOTOS

After three and a half years at the helm, Raf Simons is leaving Dior, the New York Times reports. His departure has come as something as a surprise, especially since Simons is now the second Dior creative director to suddenly depart in five years. It's worth noting the he's leaving on his own terms, as opposed to his predecessor, John Galliano, who was fired from the house after a video appearing to show the designer making anti-semitic remarks was released. There is no official replacement yet, and Simons said of his departure, "It is a decision based entirely and equally on my desire to focus on other interests in my life, including my own brand, and the passions that drive me outside my work."

The brand reportedly flourished during his tenure as creative director, so it'll be sad to see him go — especially as he was the genius behind many a gorgeous dress over the past several years. The dress Jennifer Lawrence took home the Oscar with back in 2013? The blush-colored ball gown Carey Mulligan wore to the Cannes premiere of The Great Gatsby ? The mermaid-esque gown Lupita Nyong'o stunned at the 2014 BAFTAs in? All designed during Mr. Simons' reign over the brand. Suffice it to say, there are a lot of reasons to mourn Simons' departure from Dior — so let's celebrate his time at the fashion house by memorializing some of his best creations!

Kate Mara has been killing it on the red carpet lately, and this delicately embroidered Dior is pretty darn pitch-perfect.

Opinions were mixed on this dress, but LBR: It doesn't get much better than delicate chainmail-inspired jewelry over a floral mini dress.

Simple perfection.

Hailee is rocking the whole futuristic look — and those boots are insane, in the best way possible.

Simple, graphic, and straight-up stylish (also, her matching orange lip is perfection).

Strange? Yes. Awesome? Also yes.

24. Nicole Kidman (also) at the Cannes Premiere of The Great Gatsby

Another epic print for his first couture collection with the brand, Simons sure took Dior's signature mid-century silhouette and made it work for him, eh?
