ruffled bibs were popular, but have since become uncommon. The wing collar originally disappeared in black tie after the 1920s when the appropriately semi-formal attached turndown collar shirt became preferred, but it has been popular with American men in a less substantial, attached form since the 1980s. However, many style authorities argue that the wing collar should remain the domain of white tie for aesthetic reasons. Etiquette maven Miss Manners is one of those who feel that while the bow tie's uncovered band is fine in a white-on-white scheme, "gentlemen with their black ties exposed all-around their necks look silly". Although some style authorities consider the wing collar to be an acceptable option for black tie shirts, they are not be worn with double cuffs or a pleated bib, and are better suited to the more formal single-breasted peak lapel jacket. They may feature a bib that is either marcella or starched and include stiff single cuffs secured with cufflinks, made of the same fabric as the bib; this type of shirt is exactly the same as one worn with white tie attire. The collar in this case is tall and stiff, which may be attached or detachable. When a full dress shirt is worn in this fashion, it is accompanied by the white marcella waistcoat ordinarily associated with white tie. Wearing white tie accessories in this manner is considered by many to be an affectation. Debrett's do not endorse the wing collar as being compatible with the black tie dress code. The more formal marcella version of the shirt fastens with matching shirt studs. These are most commonly in silver or gold settings, featuring onyx or mother-of-pearl; various geometrical shapes are worn, e.g., circles, which are most common for studs, octagons, or rectangles, which are most common for cufflinks. There has been no consistent fashion preference for gold or silver, but studs with mother-of-pearl are more formal and therefore often associated with white tie. The soft-front pleated version of the shirt should be fastened with mother-of-pearl buttons, typically supplied with the shirt on a separate strip of fabric. Alternatively, a fly-front shirt, appropriate with both the marcella and pleated bibs, conceals the placket for a more minimalistic look. There are several types of cufflinks that may be worn with black tie. The most formal and decorative are the double-panel type, which dress both sides of the cuff and are
