How it's used

This term is a collective noun that covers both undershirts and underpants, making it a very convenient way to refer to one's undergarments as a whole. It is frequently used when packing for a trip or doing laundry, where the distinction between the top and bottom pieces is less important than the category itself. While it is perfectly standard in casual speech, it sounds slightly more informal than using the specific terms separately.

Common mistake

Do not confuse this with the Mandarin term 內衣褲, which is understood but sounds formal or foreign in a typical Hong Kong household setting. Using 底衫褲 is the most natural way to refer to these items in daily life.
