Fragrant neckwear is a term used to describe leis and LEI necklaces. Leis are traditional Hawaiian garlands made of flowers, leaves, shells, or feathers, while LEI necklaces are usually made of beads or shells. Both leis and LEI necklaces are often given as gifts and are associated with the Hawaiian culture. They are also known for their fragrant scent, which is why they are referred to as fragrant neckwear.
