Oliver Spencer 's trousers are named 'Fishtail' because of the notched waist detailing. The fit is slim with a gentle taper towards the ankle, making them the perfect base layer to both smart and casual looks. Dress them up with a shirt and brogues, or with a heavyweight-knit and boots. Shown here with a Massimo Alba shirt , Oliver Spencer blazer and Grenson shoes .
