The royal ceremony is also one of the factors that reflect the cultural imprints that contribute to the rich and diverse identity of the heritage of Vietnam's national costumes. Studying the decorative arts on royal vestments of the Nguyen dynasty is to find the quintessence, spiritual values, and aesthetic values through the expression of content and form. The royal ceremony of the Nguyen Dynasty (1802 - 1945) still has many historical sources, photographic documents, and preserved heritages. These are the works of art of the ancients with a delicate combination of decorative shaping and sewing, embroidery and weaving techniques, creating a special space bearing the imprint of the royal fine arts of the Nguyen Dynasty.
