Don't wear long sleeves, you need a white collar and a red bow tie. Wear a skirt and brown-gray stockings. The color of stockings will match the clothes of bachelor/master. Wear well-behaved and formal leather shoes, high heels or low heels are good.

If you don't have a suitable collar coat, wear a black coat with a big round collar to prevent it from leaking from the neckline. Girls with big faces and messy hair can wear bachelor's/master's hats. If her face is small and delicate, she can tie a beautiful flower bun at the back of her head and pull out a little hair from her bangs and sideburns. Bring simple and ingenious jewelry.
