denim skirt

Double denim1 – a style of dress in which a denim jacket or shirt is worn with a pair of jeans or a denim skirt, often regarded as a breach2 of fashion etiquette3.

双牛仔——指一种穿衣风格，用牛仔夹克或牛仔T恤配牛仔裤或牛仔裙，这种搭配通常被认为是违背时尚标准的。

Don't let your denim dress you down: Had this girl traded her ratty skirt and fuchsia leggings for a crisp pair of cropped jeans, she'd be rocking a chic stripes-and-jeans combo.

别让牛仔裙把你穿掉价：如果这姑娘能将她破破烂烂的裙子和紫红色的裤子换成一条活泼的九分牛仔裤，将变成别致的条纹与牛仔混搭。

Since they are typically made of a denim/ spandex blend and simply resemble regular tight pants, they are often worn on their own as opposed to under a skirt or dress.

由于当时的紧身牛仔裤是由牛仔布加氨纶的材料制成，而且与常规的紧身裤很相似，因此可以单独穿着，不用搭配裙子。
