In November I usually start to pull my sweaters out of the wardrobe.
I love warm wool sweaters and match them with chino pants.
I wear a brick-colored sweater by Brooks Brothers, a classic grey from Alan Paine (a classic for a cashmere pullover), or one by Gant in light colours (a brand often associated with preppy style).
Merinos wool, English wool, cashmere, in harsh winters you just can not do without!
