But the design is so classic that it's super easy to find without resorting to dropping major cash for the Tom Ford original!
We found two equally affordable options that are super similar to Kate's dress.

Beyoncé knows how to keep the whole world at her fingertips!
While many pop stars tend to wear the same costumes throughout their tour runs, Bey prefers more variety, and she's been giving us one seXXXy look after another on the Mrs. Carter Show World Tour.
The second show-stopping number — a red gown with double thigh slits (above bottom) — was made especially for her (of course!) by Israeli designer Alon Livné. The 27-year-old designer was personally recommended to Bey by her stylists, Ty Hunter and Raquel Smith.
"They asked me if I could do something special. I said yes, of course."
Even though he did not have his own studio in New York where he could create the costumes, Bey's peeps provided him with everything he needed! Alon explained:
"I think the fact that they were willing to help me make these dresses, and to give me a studio, was so amazing. I mean, it’s Beyoncé. She can go anywhere from Chanel to Givenchy and pick whatever she likes, and she helped me."
Yet another reason to love Queen Bey, like you needed one!
Alon also revealed that he's designed a striking red, Swarovski crystal-encrusted bodysuit for the diva, which will make its debut during some upcoming shows.
Check out the sketches as well as details of the latest costumes in the gallery (below)!
