For tuxedo wear a casual vest (or Spanish belt) is a must-have
accessory for tuxedo wear.

When worn together the vest and the Spanish belt should be consistent in colour and
material. Vests are leaner than waist belts, because they focus on the face rather than the
waist, so it’s smarter to wear a tuxedo belt for leaner gentleman. The tailoring of th evest
depends on how the jacket is buttoned. If the jacket is one-buttoned, the vest is deeper
tailored, if it is three-buttoned then it is higher tailored. The deeper tailored vests have three
or four buttons. For wedding wear, the colour of the tuxedo vest matches th bride’s dress.
Casual vests are typically made off silk or satin, mostly monochrome but they can also be
jacquard printed.
