A man's suit can be the hardest working piece in his wardrobe: it's all down to combinations and details. Go for the classic shirt and tie accompaniment for a sharp business look, or introduce a fine-knit sweater as your base layer to add a dressed-down element that remains refined. A leather briefcase and Oxford shoes will further ensure things are kept in the sartorial zone.
For something a little more casual, swap out matching trousers for a pair a shade darker - but in the same colour. This will instantly take your look down a notch in terms of formality. Now the details can come into their own. Pair your tailoring with sneakers and a modern leather tote for an on-the-go weekend look that stays high in style.
