Crafted from fine merino wool, the Blackhall zip-neck jumper from Reiss should be considered a signature of the fashion house; it's featured in the British designer's assortment enough seasons after all.

Lightweight and signed off with a cosy-yet-contemporary feel, it's rendered in a variety of colours that'll always look great layered beneath a dark grey suit and box-fresh trainers for a tailored outfit that's smart-casual appropriate.
