Shirts are essential pieces in any man’s wardrobe, whether straight, fitted or oversized. They can be worn in plain or print versions, alone, or layered over or under other pieces, with something to suit every style. Denim shirts come in a variety of washes, from bright ecru to deep black and flecked blue. In cotton, they come in crisp poplin and light cotton veil. In linen, they keep summer outfits cool.
