Peanut butter and jelly, milk and cookies...there's nothing we love more than a great collaboration, but nothing beats an upscale runway designer paired with a mass-market retailer. Lucky for us, and our bank accounts, Derek Lam for DesigNation has finally launched at Kohl's. Just in time for spring, you can snatch up some seriously chic new pieces to add to your warm weather wardrobe, all at prices that won't break the bank. The stunning collection was inspired by Derek's visit to Rio de Janeiro in Brazil. "Rio is one of those wonderful cities that has so much color and life, with a jungle meets city atmosphere. It's modern and timeless at the same time, and a wonderful place to find inspiration," the New York-based designer said. With pieces that transition seamlessly from day to night, the Derek Lam for DesigNation collection will easily become wardrobe staples. Pick them at a Kohl's store or online at http://www.kohls.com/.
