Men should wear suits or casual clothes with a little taste, and women should wear some festive colors and be beautiful. Engagement should not be too formal. I don't think we should wear red and pink. After all, it's engagement! You can be elegant and generous! If you like Chinese style, I suggest you wear cheongsam! The color of the short paragraph can be light pink, gold, or some light flowers. Want to be fashionable and in line with the current trend, that is a short white dress! It can be an H-shaped skirt with a high waist! The material with a little georgette will be better, and the fabric should not be too soft! That would be too bad! Or a fluffy skirt, it will look sweeter! You can also choose some patterned fabrics with light flowers. It is good for boys to have a relatively simple suit, as long as it is not khaki or dark blue. Accessories are also important! The finishing touch! Don't exaggerate! Just bring an earring. . . I hope I can help you! It depends.
