A solid assortment of well made Polo Shirts is the backbone of any good casual wardrobe. Go for plain, block colours for maximum versatility and stock up on black, navy, grey and white in particular – chances are, these are the ones that’ll see the most daily action.
Don’t fall into the trap of thinking Polo Shirts should be cheap, though. Sure, you can pick up a plain polo from a high-street chain for less than a good coffee, but will it last more than two washes before becoming a crop top? Probably not.
