How it's used
Originating from Cantonese slang that combines the word for old with the character for west, this term specifically refers to a Western style suit. It carries a slightly playful or informal tone, so it is best avoided in highly formal business settings or when speaking to a superior. While it can also refer to a Westerner, that usage has become significantly less common in modern speech compared to its primary meaning of formal attire.

Common mistake
Do not confuse this with 西裝, which is the standard, neutral term for a suit. Using 老西 in a professional interview or a serious meeting may sound overly casual or even disrespectful depending on the context.
