These blue Balenciaga Straight Leg Tailored Trousers are made from a cotton blend fabric and feature a mid-rise waist with belt loops, button and concealed zip fastening, side hip pockets and centre pleat detailing. These trousers are essential for any Sloane Ranger gent. For if we refer to the Brown's book on lavish living, it clearly states you must own all the B's: bottles of bubbly, your Bordeaux bungalow and of course – Balenciaga.
