Liven up your smart separates, in and out of the office, with a purple shirt. To complete an influential boardroom outfit, choose a regal hue in a flattering slim-fit shape, and look out for subtle all-over prints that elevate the design. Soft pastels are perfect for warm weather events, especially styles with fun floral prints and short sleeves. For just a hint of colour, choose a pale lilac to slip on with tapered trousers and brogues.
