How cashmere should fit

A classic jumper should skim the body with a little ease at the chest. Cashmere relaxes slightly with wear, so do not size up unless you want an oversized look. Superfine knits are cut closer; chunky cables are cut generous.

Between sizes?

Take the smaller size for a fine layer under tailoring, the larger for a jumper worn alone. Read the N.Peal size guide and the country guides for the US, Japan and Canada and Australia.
