A divided skirt (also called a culottes or skort) that has the external appearance of a skirt classifies under the skirt subheadings (610451–610459) rather than the trouser subheadings. If the garment clearly has separate leg sections and resembles trousers in construction, it would move to 610461–610469. CBP rulings on divided skirts focus on the garment's visual appearance when worn.

If the jacket and skirt are made of the same knitted fabric, presented together for retail sale, and intended to be worn as a coordinated outfit, the set classifies as an ensemble under the ensemble subheadings (610422–610429) rather than as separate garments. If they are sold separately or differ in fabric, each piece is classified individually under its own garment subheading.
