A key tailoring piece this season, the overcoat is the one to turn to, whatever your plans. Versatile is its middle name and you'll want to take this outside. Early morning meeting? Weekend drinks with the boys? Layer over your work suit or throw on over plain tee, jeans and trainers - it just works. Single breasted with a notch lapel, keep it classic in black and navy or go neutral with grey or beige shades.
