British high street chain Topshop has unveiled the four mini-collections that make up its Spring 2011 offering. This season, you’ll find Swedish Summer, Snake Valley, Graduation, and New Age Constellation. Each collection focuses on a different theme. While Swedish Summer (above, yellow background) focuses on 1970s-inspired floral dresses, embroidered denim, and delicate crochet, Snake Valley (below, blue background) focuses on the flowing maxi skirts and silk kimonos one might find at a summer music festival. If you prefer a different vibe, Graduation (below, red background) offers preppy prints and bright accessories, while New Age Constellation (below, grey background) centers on color-block dresses and clean, futuristic silhouettes. Pieces from Swedish Summer, Snake Valley, and Graduation are available at Topshop stores, as well as online at Topshop.com, now. New Age Constellation will arrive in the next few months.
