Billie was seen leaving Dirty Martini after launching her new fashion range with In The Style, and she proved that there's no promotion like self promotion as she donned the stylish black jumper.
Emblazoned with the words: "Prosecco Made Me Do It," Billie proved that sometimes less is more as she teamed it with leather-look pants.
If you're lusting after it, you're in luck, as it's part of Billie's new range and can be bagged for just £19.99.
Billie is following in the footsteps of former TOWIE co-star Lauren Pope and Geordie Shore's Charlotte Crosby as the latest celeb to join forces with the online fashion label.
She previewed her new collection to the press (including Reveal) and we were lusting over rails upon rails of her brand spanking new designs.
Billie made an outfit change on the day too, arriving in a 70s-esque paisley playsuit before later opting to wear a sexy LBD complete with criss-cross detailing. Beaut!
