We don't need a book to tell us how many shades of grey there are – just take a look at our grey men's shirts to find deep charcoal, light ash, smoky silver... (we could go on). And the styles are just as wide-ranging. We've got slim-fit options with herringbone finishes for a supremely smart feel. You'll also spot washed denim overshirts with utilitarian cuts that are ideal for laid-back days. Look out for contrasting colour plackets, tonal buttons and logo embroidery that adds a dash of detail to some of our favourites. Need something to elevate your best weekend joggers? Choose a light grey men's shirt with a woven-knit texture to create a sports-luxe look. For days in the office, try a men's dark grey shirt with tailored trousers to slide seamlessly from the water cooler to the whiskey bar.
