Lucy & Co. The You're a Square Reversible Teddy VestThe You're a Square Reversible Teddy Vest is full of cinnamon tones and green greens that are as warm as a cup of tea on a cool autumn day! This warm and fuzzy dog jacket is sweeping winter wardrobes and blanketing its wearers in a big bear hug! We had the on the go dog in mind when we designed these: zip closures and a leash clasp opening on the back side of the vest make getting out the door easy.
