To tie a silk neck scarf, fold it lengthwise into a narrow band, drape it around your neck with one end a little longer, then finish with a knot that suits your neckline: a side knot for an open collar, a bow for a blouse, a loop knot for a coat. A long, skinny silk scarf is the easiest to tie because the extra length lets you wrap twice and double knot, which is what keeps silk in place. The Zimmermann printed silk neck scarf, at 180 by 18 cm, is a good example, and you will find more shapes in the designer scarves edit.
