What’s more, Cushman’s dress was not put together by a fancy, high-end designer like Kate’s, it was purchased off-the-rack from Kleinfeld’s in Brooklyn.

Have a look at the photos above and below to judge for yourself, but it does appear there’s a striking resemblance between the two gowns. Here’s Cushman describing her shock at seeing Kate’s dress for the first time:

“Glued to the television early Friday morning, I watched as she emerged from her hotel and tucked herself into the car waiting to whisk her to Westminster Abbey. The camera zoomed in, straining to catch details of the dress, the train, the veil. As it became easier to see, commentators instantly and unanimously declared the dress a success. So modern, yet classic and romantic. The perfect choice.”

“But I was stunned. Kate was wearing an exact replica of the wedding dress I had worn — and I was about to celebrate my 20th anniversary! A dress I had picked up in 1991 at Kleinfeld’s in Brooklyn, off the rack and on sale (albeit in the high-end department).”

“I grabbed my wedding photos and showed them to anyone who would look. Yes, they gasped, it was the same lace bodice with the plunging neckline, the slight collar, the bustle in the back anchored by buttons. No, my lace hadn’t been specially designed for me, and my train was considerably shorter. But the cut and design were almost identical.”
