Jack Frost has come a-nippin’, and Harry Barker’s new Fair Isle dog sweaters, in classic stripe (below) and party stripe (above), can bring a bit of classic cool to your dog’s winter look. The acrylic sweaters are machine-washable and can be personalized with up to 15 characters. (“DANG, IT’S COLD” just fits, in case you’re wondering.) Check them out at Harry Barker.
