Shetlands, and these look like "Shaggy Dog" models. Hard to believe that as a teen I could actually wear one at night in summer in New York. Now, you could wear one in place of an overcoat in winter here. Still beautiful, even if only on a shelf.
Now here is some really beautiful creativity in menswear. I love the way the blue and white stripe shirt bring out the pattern in the blazer, and the browns will not overpower the outfit, since the pants are much lighter.
