"HAPPY BIRTHDAY to my best friend in the whole wide world @nataliehalcro," Liv wrote on Instagram, captioning this gorgeous snapshot of her and Nat catching some sun in complementary pastel-toned bikinis. In pretty classic fashion for these two, Liv sported a solid print while Nat went for a patterned swimsuit instead.
"NAT & LIV x COMINO collaboration is now live for purchase everyone! @comino.couture," Liv wrote on IG. "We had such a great time collaborating our style with Sarah's at Comino. Hope you all like the peices! THANK YOU to all our friends & family who came to our launch this night! Love you all!"
But in the most fashionable way!
