A bǎi zhě qún is a skirt made of many narrow, evenly spaced vertical folds—like an accordion—that create volume and movement. The name literally breaks down as bǎi (hundred), zhě (fold/pleat), and qún (skirt), suggesting abundance of pleats rather than exactly one hundred. These skirts are commonly made from lightweight fabrics like polyester, cotton, or silk and are popular in both casual and formal wear, especially among young women and girls.

In China, pleated skirts often appear in school uniforms, dance costumes, and seasonal fashion—such as spring or summer outfits—where their breezy silhouette suits warmer weather. They may be worn with blouses, sweaters, or t-shirts, and come in various lengths: mini, knee-length, or midi. While traditionally associated with femininity and elegance, modern styles include asymmetrical cuts or bold prints, making them versatile across ages and occasions.
