Polyvore and Rebecca Minkoff have gotten together to see if you have what it takes to design the next IT bag. The challenge, if you choose to accept it, is to take inspiration from Rebecca’s “Morning After Clutch,” and redesign it. The “MAC” has been worn by celebs such as Reese Witherspoon, Keira Knightley and Shenae Grimes, and is an iconic bag in its own right. All of the elements — hooks, studs, zippers, tassels, feet and leather — are provided for you on the Polyvore site. You just have to put your design together. Ten finalists will be picked by Rebecca herself and the winner will be chosen by user votes on Facebook. The winner will have their bag shown during New York Fashion Week and it will become available for sale in March! So, will you put your creative skills to the test?
