The depiction of characters' costumes in the Red Chamber has played a great role in shaping plump and vivid characters. The costumes in a dream of red mansions are colorful and dazzling, and they look roughly the same. In fact, if you carefully taste them, you will find that everyone's clothes reflect their own unique style. Baoyu's clothing is obviously feminine, while Xiangyun's is masculine; Daiyu's clothes are simple and elegant, and there are not many decorations, while Xifeng's clothes are gorgeous and ornate; Baochai's dress has a mature charm, while Fangguan retains the childishness of children. Not only are people with different personalities like this, but people with similar personalities also have different costumes: Baochai and xiren are gentle and smooth, but one is dignified and simple with a lady, and the other is generous and decent with a maid; Dai Yu and Miao Yu are both "aloof", but one wears elegant clothes on earth and the other wears fairy clothes and shoes ... each has its own form and style. The costumes of the characters set off each other with the characters' images, achieving the harmonious unity of the inner and outer characters. I think the description of characters' costumes in A Dream of Red Mansions can not only set off the characters' personalities and reflect their style and status, but also deepen the characters' images and leave a clear impression on readers through detailed description. Clothing is integrated with the whole character and closely related to the character's personality, which gives the character a rich and substantial three-dimensional sense. It's really an innovation of Cao Xueqin, and it's a rare wonderful stroke in famous works.
