Cufflinks and studs are generally reserved for formal dress rather than everyday business clothing. Tuxedos should always be accessorized with cufflinks and studs. A mother-of-pearl set of cufflinks is appropriate for white tie events, while plain silver or a tasteful color like black onyx can work with black tie occasions. for the more adventurous gentlemen, opt for novelty cufflinks and studs that reveal the real you.
If you’re attending a less formal occasion in a dress shirt with French cuffs, it can be accompanied by silk knots or a variety or novelty links that represent your interests, hobbies, or occupation.
