This two-piece set pairs a knitted outer layer with a separate inner layer, each chosen for a different role. The outer layer is made from 6% wool, 20% nylon, 54% polyester, and 20% acrylic, a knit blend that gives the piece its lightweight, thin feel while holding the shape of an open-front cardigan. The inner layer is 95% cotton and 5% spandex, a soft, stretchy fabric that sits close to the body and moves with you. Together the two layers suit the retro, casual, and relaxed aesthetic of the piece, and the thin knit construction makes it easy to wear as a layering option for autumn.
