Collar lapels are satin or grosgrain. In warmer months some men choose the white or ivory tuxedo jacket. For very formal evening weddings, a groom may choose a full dress tailcoat, which should be worn with a vest , wing collar shirt and white pique' front and white box tie. For formal morning weddings, the morning coat is worn with black or grey striped trousers, wing collar shirt and ascot. Start with a formal shirt.
Most grooms choose classic white, although black is a high fashion color for avant garde weddings.
Plain or pleated fronts and French cuffs add an elegant touch. A turn down pointed collar looks best with a black bow tie, preferably one you tie yourself. Single breasted jackets for evening or formal wear look best with a vest and ascot. Black once again, is the most common color, but sophisticated grooms looking for that old world styling may opt for gold, silver or even striped. Less expensive vests may use a lower grade material for the back which doesn't show while the groom is dressed in a full tuxedo.
