Swords of Legends is a Chinese historical drama that tells the story of an ancient swordswoman named Su E.

The main character, Su E, wears a blue outfit and headdress, which holds significant meaning in traditional Chinese culture.

In ancient China, blue was considered a lucky color that symbolized tranquility, peace, and wisdom.

Therefore, Su E's choice to wear blue not only showcased her beauty but also expressed her pursuit of peace and wisdom.

Furthermore, Su E's attire has a historical background.

In ancient China, women would often wear elaborate clothing to display their status and wealth.

However, Su E's blue outfit is more modest and understated, perhaps because she plays the role of an ordinary woman rather than a wealthy or noble one.

Overall, Su E's blue outfit and headdress are an important element in the Chinese historical drama Swords of Legends.

They not only represent the character's image and personality but also reflect the understanding and use of colors and clothing in traditional Chinese culture.
