Something blue! Stun in Paris' chiffon bridesmaid dress by Alice + Olivia

Paris Hilton must be the first bridesmaid to ooze sex appeal in obligatory dress.

The hotel heiress stunned at her sister Nicky’s wedding in a blue chiffon wrap bridesmaid dress which was custom created for her by one of her favorite brands, Alice + Olivia.

Showing off her svelte midriff with its embellished cinched-in waist belt, Paris kept her flaxen locks in a flowing, curly style and posed with a sultry expression across her face.

Flattering her skin tone with its summertime perfect cornflower blue hue, the ruched chiffon gown couldn't have been a better choice for the London wedding and Paris did a great job of being a bridesmaid to her sister in her custom Valentino wedding dress.

Sadly, Paris' dress is not available to purchase online, but you can shop the look below from the likes of J. Crew and Monique Lhuillier in the edit below... particularly if you're a bridesmaid at a wedding this summer.
