Pippa Middleton, speaking at her first public event, made a good-humored quip about one her most infamous moments – nearly upstaging her sister in a curve-hugging Alexander McQueen gown at the royal wedding in 2011.

Pippa Middleton On Bridesmaids Dress

Middleton’s bridesmaids dress at the wedding between Kate Middleton, Duchess of Cambridge, and Prince William made her an instant celebrity. The 30-year-old aunt to Prince George recently admitted that fame is a tricky thing.

"As I have found out, recognition has its upside, its downside, and — you may say — its backside," she joked about her eye-catching wedding ensemble at the Women in Advertising and Communications group dinner in London Tuesday.

Middleton added that while at the time she was “glad [the dress] fitted," she thought "in retrospect, it fitted a little too well."

Guests of the dinner were impressed with Middleton’s candor and ease on the stage in her first public speech. In addition to cracking about her dress, she commented on her career since the wedding, which included the disappointing flop of her entertainment book, Celebrate.

“It was the first time she’s made a speech of this kind but you wouldn’t have known it, she was so relaxed. It was unbelievable how open she was – I don’t think anyone was expecting that,” a guest told The Mirror. “She talked about the royal wedding and her career since. She came across as really grateful for the opportunities but also talked about the pitfalls of her position.”
