‘长袜’ (cháng wà) literally means 'long socks' — the character 长 (cháng) means 'long', and 袜 (wà) means 'sock'. It specifically refers to knee-high socks that extend from the foot up to just below or over the knee, distinguishing them from ankle socks (短袜, duǎn wà) or thigh-highs (过膝袜, guò xī wà). These are commonly worn in cooler weather, for formal attire (e.g., with skirts or suits), or as part of school or sports uniforms in China.

In everyday usage, 长袜 is a neutral, standard term understood across all age groups. It appears frequently in clothing descriptions, shopping contexts, and seasonal advice. While it’s not gender-specific, it’s often associated with women’s fashion — though men also wear them, especially in winter or for cycling. The word does not imply material or pattern; those are specified separately (e.g., 毛线长袜 ‘wool knee-high socks’).
