Rihanna's Met Gala outfit got a lot of attention last night, as it should.

While it may not come as a huge surprise that her extremely massive yellow robe took quite some time to create, it may have taken even longer than you think. During an interview with Vogue's André Leon Talley on the red carpet, RiRi revealed that not only did her robe take years to make (yes, that's plural), but it was all stitched together by one woman—designer Guo Pei.

"It's a miracle how it happened actually," she tells Talley. "I saw this beautiful piece on the Internet. I was looking through, you know, researching Chinese couture...It's handmade by one Chinese woman. It took two years to make this."

Amazing.
