Swanky, often used informally, describes something or someone that is stylish, luxurious, and often ostentatious.
It implies a sense of affluence and sophistication, sometimes with a hint of showiness. A Swanky establishment aims to impress with its high-end decor, exclusive atmosphere, and expensive offerings.
The term can also refer to someone who is elegantly dressed and behaves in a way that suggests they belong in such environments.
While generally positive, 'swanky' can sometimes carry a slightly negative connotation, suggesting pretentiousness or excessive extravagance.
