Blanket jackets saw some popularity this current season among the indie fashion crowd, with designers making them for both men and women. Krane for example, used blankets from Hudson’s Bay Company quite extensively and even created a special jacket for them using one of their grey/black patterns. Ralph Lauren had one too, and Opening Ceremony made some crazy ones from Pendleton fabrics. They’re not something I’d personally wear, but I do enjoy the history behind them.
