The TOWIE stars sported deep matching tans and oh-so-chic outfits to attend the launch party at London's Sanderson Hotel on Wednesday evening (28 January).
Sam looked fantastic in ripped blue jeans, a very low cut top and sleek fitted white blazer, teamed with heels. Very Kim K, no?
Mum-of-one Billie, meanwhile, flashed her tum in a white polo neck crop top, matched with olive cropped skinny trousers and heels. She's just back in the UK from a sun-drenched holiday to Dubai. Lucky thing!
And, of course, both sisters were wearing Sam's fake lashes!
Sam told Reveal that she'd always wanted to have her own lashes range, particularly following the success of her debut perfume, La Bella, last year.
She's also passionate about fake lashes because she doesn't have lashes of her own. Sam has been quite vocal about the fact she picked out her natural lashes as a child.
"I don't have any natural lashes myself, so I've spent thousands on fake lashes over the years and I've worn them since I was 16. I know what I like in a lash, I don't want the strip to scratch and I want the glue to be good," she said.
"I can't have latex in my eyelash glue because my eyes are sensitive, it irritates them. Lashes are such an important part of my life so I wanted my collection to be perfect."
