There's nothing like the color red to make a woman feel sexy, empowered, and confident. Hell, red lipstick alone works wonders! So it's no wonder L'Oreal Paris opted for the color on International Women's Day to host The Red Obsession Party, celebrating their official sponsorship of Paris Fashion Week. Supermodels and A-listers alike came out to toast the French beauty brand, appropriately sizzling in scarlet. Karlie Kloss, Eva Longoria, Irina Shayk, and even Bradley Cooper made appearances at the Parisian fête, but frankly we're surprised Christian Grey didn't pop up somewhere in the red room.

Who was there: Guests included Doutzen Kroes, Isabeli Fontana, Bianca Balti, Karlie Kloss, Irina Shayk, Natasha Poly, Cyril Chapuy, Soo Joo Park, Barbara Palvin, Chris Brown, Dana B, Eva Longoria, Ophelie Guillermand, Rose Bertran, Thylane Blondeau, Vashtie Kola, Bradley Cooper, Daria Strokous, Kristina Bazan, Lara Stone, Leila Bekhti, Lewis Hamilton, Luma Grothe, Miles Bugby, Olivia Culpo, Sasha Luss, Taylor Hill, Alex Pettyfer, Ellen Von Unwerth, Gabriel-Kane Day-Lewis, Hailey Baldwin, and Hari Nef.
