Cufflink

Cufflinks are used to secure button shirt cuffs and may also be an item of jewellery for boys and men. Cufflinks can be manufactured from a variety of different materials, such as glass, stone, leather, metal, precious metal or combinations of these. Securing of the cufflinks is usually achieved via toggles or reverses based on the design of the front section, which can be folded into position. In addition, there are also variants with chains or a rigid, bent rear section. The front sections of the cufflinks can be decorated with gemstones, inlays, inset material or enamel and designed in two or three-dimensional form.

Cufflinks are designed only for use with shirts which have buttonholes on both sides but no buttons. These may be either single or double-length ("French") cuffs, and may be worn either "kissing," with the ends pinched together, or "barrel-style," with one end overlapping the other. The "barrel-style" was popularized by a famous 19th century entertainer and clown, Dan Rice; however, "kissing" cuffs are usually preferred.

Cufflink designs vary widely, with the most traditional the "double-panel", consisting of a short post or (more often) chain connecting two disc-shaped parts, both decorated. Whale-back and toggle-back cufflinks have a flat decorated face for one side, while the other side shows only the swivel-bar and its post. The swivel bar is placed vertically (aligned with the post) to put the links on and off, then horizontally to hold them in place when worn. The decorated face on the most visible side is usually larger; a variety of designs can connect the smaller piece: It may be small enough to fit through the button hole like a button would; it may be separated and attached from the other side; or it may have a portion that swivels on the central post, aligning with the post while the link is threaded through the button-hole and swiveling into a position at right angles to the post when worn.

Links of knotted brightly coloured silk enjoyed renewed popularity in the 1990s, joined by an elasticated section.

The visible part of a cufflink is often monogrammed or decorated in some way, such as with a birthstone or something which reflects a hobby or association. There are numerous styles including novelty, traditional, or contemporary. Cufflinks can and have been worn with casualwear, informal attire or business suits, all the way to very dressy styles such as semi-formal (black tie or Stroller), and formal wear (morning dress or white tie), where they become essentially required and are matched with shirt studs. Colourful and whimsical cufflink designs are usually only suitable for casual and relatively informal events, and signals someone who is fun-loving, approachable, and friendly. However, formal wear has stricter expectations, with pearl cufflinks being preferred for white tie events Traditionally it was considered important to coordinate the metal of one's cufflinks with other jewelry such as watch case, belt buckle, tie bar or rings. Sartorial experts prescribe gold to be worn during the daytime and silver for evening wear, but neither expectation is considered as critical as it once was.
