Which word would best describe an ostentatious lifestyle?

An ostentatious lifestyle is characterized by a desire to attract attention and admiration through displays of wealth and extravagance. The term "extravagant" captures this essence perfectly, as it implies spending lavishly and indulging in an abundance of luxury that seeks to impress others. Such a lifestyle often involves showy consumption, whether in terms of clothing, homes, or experiences, highlighting a lack of restraint and a penchant for the dramatic.

The other options describe contrasting qualities. "Modest" suggests simplicity and restraint, emphasizing a lack of pretentiousness, which is the opposite of ostentatious. "Practical" leans towards functionality and sensibility, ignoring the flamboyance associated with ostentation. "Unassuming" indicates a lack of desire for attention or fame, aligning further away from the characteristics of someone leading an ostentatious lifestyle. Thus, "extravagant" is the most accurate choice to describe such a lavish and attention-seeking way of living.
