Polynesian neckwear, also known as leis, are traditional garlands of flowers, leaves, shells, and other natural materials that are worn around the neck. Leis are a popular symbol of hospitality in Polynesian cultures, and are often given as gifts to visitors or exchanged between friends and family members. They are typically made with brightly colored flowers, such as hibiscus, plumeria, and orchids, and are often scented with fragrant oils. Leis are an important part of Polynesian culture and are used to celebrate special occasions, such as weddings, birthdays, and graduations.
