Which word describes something that is showy but cheap and of poor quality?

The word that describes something showy but cheap and of poor quality is "tawdry." This term specifically refers to items or styles that exhibit a superficial flashiness, often characterized by gaudiness or a lack of refinement. Tawdry items may catch the eye due to their bright colors or extravagant designs, but they usually lack true quality or worth, making them appear cheap in the eyes of discerning individuals.

"Elegant," in contrast, suggests a sense of refined beauty and grace, embodying high quality. "Grandiose" often refers to something impressive or magnificent, but it may not necessarily imply poor quality; it can indicate something that is overly elaborate or ambitious without the negative connotation. "Opulent" implies wealth and luxury, often associated with high-quality materials and craftsmanship, rather than cheapness. Thus, "tawdry" is the most accurate term to describe something that is both showy and of poor quality.
