Got the memo? Calvin Klein Jeans is majorly back this summer (Harry Styles and soccer star Neymar in "Obsession" sweatshirts, cool girls like Leomie Anderson wearing Nike crop tops with all Calvin err'thang). Then, last night in London, the label and My Theresa held a party to celebrate Lottie Moss' new role as the face of the Calvin Klein Jeans Re-Issue Project (following in the high heels of her big sis Kate). Check out who else was there (and maybe dig out that old bottle of Eternity).
