It's only appropriate that we celebrate National Sibling Day with two of the coolest celebrity sisters in two of the coolest crimson frocks.
At an event in Los Angeles both Elle Fanning and Kate Mara chose red party dresses--Fanning's is Versace while Mara's is Christian Dior--that they each accessorized with gold metallic accessories. Coincidence? We'd like to think not, but only because we're imagining the text message convo that went on between the two to coordinate their outfits. ("Hey K8, what r u wearing tn?" ... "On Wednesdays we wear red, Elle. You know that.")
Either way, we totally plan on joining the red dress club this spring with the raddest red dresses in the slideshow from brands like Armani Jeans and Isabel Marant. Check 'em out while you say bye to your pretty pinks and boyish blues.
