Pippa Middleton can joke about the bum that made her famous.
The royal sister-in-law talked about the bridesmaid dress she wore as her sister Kate's maid of honor at the 2011 royal wedding, while speaking at a dinner for Women in Advertising and Communications in London Tuesday night, according to E! Online.
"As I have found out, recognition has its upside, its downside, and -- you may say -- its backside," Middleton said, referring to the ivory Alexander McQueen dress she wore at Kate and William's April 2011 wedding.
I totally knew it was an Alexander McQueen dress. I could just tell the minute I saw it.
Middleton, 30, became an instant celebrity in the curve-hugging dress, which apparently flattered her posterior.
Middleton said she was "glad it fitted" her then, she jokingly added, "in retrospect, it fitted a little too well."
According to The Mirror, Middleton also talked about the poor sales of her 2012 party planning book "Celebrate," which only sold 18,000 copies.
"She talked about the royal wedding and her career since," a source reportedly told The Mirror. "She came across as really grateful for the opportunities but also talked about the pitfalls of her position."
