Slim Fit – Cut closer to the body, and typically with a shorter jacket. Not just for slim guys: if you have broad shoulders then size up.
Wool – The most versatile choice, wool is the classic tuxedo material and it’s great for any season.
Navy – A good way to introduce some color without sacrificing formality.
Peak – The most formal type of lapel, the peak shape especially draws the eyes up towards your face. Best for black tie events.
