British style made in Britain, and that's how it will stay. Our Waistcoats, or Formal Vests as they are called across the pond, add an air of sophistication to your wedding suit. At Sir Plus, we believe in looking the part on the big day - play around with colours and textures, or wear a jacket in a neutral shade heightened with a pop of a colourful Waistcoat.
