There’s something about great knitwear that has us going back to buy two, three, even four of the same style in different colours - when the materials are A-grade, the fit is spot-on and the cut of the body and sleeves makes it seem made for you.

We asked Carolyn Yim, founder of menswear label Dreyden - watch this space when it lands on Lane Crawford in just a few weeks - to give us an idiots guide to keeping your cashmere and knitwear at its best.
