What is the definition of something characterized by vulgar or pretentious display; designed to impress or attract notice?

The term that accurately captures the definition of something characterized by vulgar or pretentious display, intended to impress or attract notice, is ostentatious. This word describes an outward show that is often extravagant and seeks to draw attention. The connotation tied to ostentatiousness frequently involves extravagance and an excessive flair intended to showcase wealth or social status.

In contrast, the other terms do not fit this definition. For instance, subtle refers to something delicate or understated, which is the opposite of a bold or showy display. Simplistic suggests a lack of complexity or depth, failing to convey the notion of extraversion or the need to attract attention. Lastly, modest describes a quality of being humble or unassuming, which also runs counter to the ostentatious nature of seeking to impress through grandiose appearances. Thus, the choice of ostentatious aligns perfectly with the described characteristics.
