Topshop has recently introduced three new items for Fall/Winter; slouchy boy shorts, a 5-pocket, western style jacket with stitchless seam pockets and boyfriend jeans all with 70's style stitching. Obviously it's not the styles that are new.

What is new is the use of something called Bionic Yarn, a product of a company called Return Textiles which happens to be co-owned by Pharrell Williams. Bionic Yarns are a sustainable fiber made from recycled plastic bottles mixed with natural fibers. The result is supposed to be a combination performance fabric that is also strong and durable.

The items are available in Topshop stores and retail at $70 – $100
