Pippa Middleton talks about her famous bridesmaid dress

LONDON, Feb. 26 (UPI) -- Pippa Middleton admits the tight white bridesmaid dress she wore to her sister Kate's 2011 wedding to Britain's Prince William may have fit "too well."

Middleton, 30, an author and party planner, received media attention from around the world for her shapely appearance in the gown.

E! News said she joked at the Women in Advertising and Communications dinner in London Tuesday about her unexpected experience in the spotlight.

"As I have found out, recognition has its upside, its downside and -- you may say -- its backside," Middleton said. Referring to the dress, she said she was "glad it fitted."

"In retrospect, it fitted a little too well."
