Nothing screams "dapper" better than grey shades. Choose a more wedding-appropriate shade by opting for silver waistcoats, which can be layered with other grey family colours for that smart, masculine monochromatic feel. This shade blends well with a soft colour motif, too, since it provides a surprisingly cool contrast with those hues. Or, dress like a royal by using silver waistcoats for elegant accents, such as emerald green ties or burgundy pocket squares. Silver waistcoats have a strong shade, but not overpowering. It provides that much needed balance and break when pairing similar colours together.
