Flowery neckwear is a term used to describe two different types of accessories. The first is a LEI, which is a garland or necklace made of flowers, leaves, shells, or other materials that is worn around the neck. The second is leis, which are similar to leis but are usually made of multiple strands of flowers and are worn around the waist. Both leis and leis are popular accessories in Hawaii and other tropical locations.
