But now the hat's designer, Philip Treacy, has spoken out, and... he seems a tad defensive.
"My inspiration was beauty and elegance. It's a 21st century royal wedding," Treacy told HollywoodLife.com.
He explained that Beatrice and her sister Eugenie did not provide any input on the designs.
"No, they didn't tell me [what they wanted] because I've known them for a long time and I wanted them to look gorgeous and beautiful," he said. "They trusted me to make them. Gorgeous and beautiful can be open to interpretation... I thought they looked gorgeous and beautiful. But no one is crying if anyone didn't."
It does seem vaguely possible that "Don't cry over a ridiculous hat" would be the Royal version of the traditional "Don't cry over spilled milk" maxim repeated to young children.
