Formal accessories overview: (by www.TuxedoPro.com)
Formal accessories include, vests, cummberbunds or sashes, bow ties, 4-in-Hand Ties, Windsor Ties, ascots, suspenders and formal jewelry.

Vest options vary from manufacturer. The fullback vest with waist adjustable straps, which is worn around the entire upper body is a great choice for all formal attire except when wearing tails. Fullback formal vests are not height adjustable and rest low on the body which is about three to six inches longer than etiquette allows. You can have a fullback vest height-altered but this will effect the overall look of the vest on the upper portion of the body, thus a backless vests should be worn with tails.

Backless formal vests are waist and height adjustable. The backless vest can be worn with all formal attire and usually features a thinner top than a fullback vest.

Cummerbunds: Also known as a sash, the cummerbund can be worn with any formal attire.

Formal Ties: The most popular formal tie is the bow tie followed by the 4-in-Hand or Windsor Tie (looks like a neck tie). A bow tie can be worn with either a vest or cummerbund. A 4-in-Hand or Windsor tie must be worn with either a backless or fullback vest. Other tie varieties include euro ties, button covers and crossover ties. Euro Ties (half an ascot) require a vest while the later can be worn with a vest or cummerbund. Finally ascots must be worn with a vest.

Suspenders: Available in either clip-on or button holed are used to hold up your trousers. Never use black suspenders on a white shirt when using a cummerbund as your chest accessory. Use only white in that instance. Otherwise suspenders are to be worn on the inside of any and all vests. On backless vests be sure to follow the cummerbund rule, white shirt = white suspender. This is because the suspenders will show only partially and make one look less formal.
