Princess Kate was the epitome of a princess bride, but it was the young woman carrying her train – sister Pippa Middleton – who unexpectedly stole the show at the royal wedding.

Middleton’s figure-flattering Alexander McQueen dress made the then-27-year-old an instant sensation (her derriere was named PEOPLE’s Top Body Moment of 2011!), inspiring multiple Facebook fan pages and Twitter accounts.

“As I have found out, recognition has its upside, its downside and – you may say – its backside,” Middleton quipped at an event in 2014, adding that the infamous couture “fitted a little too well.”

Not even best man Prince Harry could hide his smile as he walked the stunning maid of honor down the aisle at Westminster Abbey!

The form-fitting, ivory satin-based crepe gown had a cowl front and 58 gazar and organza covered buttons, mirroring big sister Kate’s dress.

Five years later, Middleton, who celebrates her 34th birthday on Sept. 6, took the wedding day spotlight once again – this time as the bride! On May 20, she and financier James Matthews said their “I dos” in a stunning private ceremony at St. Mark’s Church in Englefield on — and it was a royal affair.
