Congrats are in order for Pippa Middleton, who only recently gave birth to her first child. Pippa and husband James Matthews welcomed a baby boy in October in the exclusive Lindo Wing, the same place that her sister Duchess Kate delivered her three children.
"Everyone is delighted and mother and baby are doing well," her rep said of the newborn, who weighed in at 8 lbs. 9 oz.
To celebrate Pippa's latest bundle of joy, we're taking a look back at the 35-year-old's style transformation over the years.
The middle Middleton child first landed on our style radar at Kate and Prince William's wedding in 2011, where she acted as bridesmaid in a slinky white Sarah Burton for Alexander McQueen dress. Since then, Pippa's turned heads at various philanthropic and social events around London, including red carpet events.
Take a look at how Pippa's style has evolved from London socialite to chic mom-to-be in the gallery above!
