Today is one of our absolute favorite actress’s 26th birthday – the always fabulous Keira Knightley. One of the gorgeous ads she filmed is our choice for the Look-of-the-Day, in honor of the beautiful Brit’s golden birthday. Here, Keira is donning a stunning scarlet silk gown, draping diamonds, swept-back hair, sleek black nails and Chanel No. 5… All a girl needs to look both sophisticated and smoking hot. (Well that, plus a body and face like Miss Knightley’s). This is the kind of advertising that reminds us why we’re subconsciously compelled to buy things we don’t need. Here’s hoping your 26th is as fun and fresh as you are Keira!
