An armband is a piece of material worn around the arm over the sleeve or other clothing if present. They may be worn for pure ornamentation, or to mark the wearer as belonging to group, or as insignia having a certain rank, status, office or role, or being in a particular state or condition. Sprung armbands, known as sleeve garters, have been used by men to keep overlong sleeves from dropping over the hands and thereby interfering with their use. Armbands may also refer to inflatable armbands used to assist flotation for swimmers or for use with sphygmomanometers, in which case they are generally referred to as cuffs.
A bracelet is an article of jewellery that is worn around the wrist. Bracelets may serve different uses, such as being worn as an ornament. When worn as ornaments, bracelets may have a supportive function to hold other items of decoration, such as charms. Medical and identity information are marked on some bracelets, such as allergy bracelets, hospital patient-identification tags, and bracelet tags for newborn babies. Bracelets may be worn to signify a certain phenomenon, such as breast cancer awareness, or for religious/cultural purposes.
If a bracelet is a single, inflexible loop, it is often called a bangle. When it is worn around the ankle it is called an ankle bracelet or anklet. A boot bracelet is used to decorate boots. Colloquially, handcuffs are sometimes called bracelets. Bracelets can be manufactured from metal, leather, cloth, plastic, bead or other materials, and jewelry bracelets sometimes contain jewels, rocks, wood, shells, crystals, metal, or plastic hoops, pearls and many more materials.
