Extravagance refers to the quality of being excessive or lavish, often in terms of spending or lifestyle choices. It embodies a sense of indulgence, where individuals or groups go beyond the ordinary to showcase wealth and luxury, often through fine dining, designer fashion, or extravagant parties. This concept can be seen in various aspects of life, from the grandiose architecture of palaces to the opulent lifestyles of celebrities. While extravagance can be a form of self-expression, it can also raise questions about sustainability and social responsibility, as it often contrasts sharply with more modest ways of living.
