What word is used to describe something that is cheap and of poor quality?

The term "tawdry" specifically refers to something that is showy in a cheap or gaudy way, often emphasizing poor quality or lack of refinement. In various contexts, tawdry can describe items, clothing, or behavior that is considered tasteless or lacking in dignity. This aligns perfectly with the idea of something being both inexpensive and inferior in quality.

On the other hand, terms like "elegant," "lavish," and "opulent" relate to notions of luxury, beauty, or richness. These words connote high quality and refined taste, which starkly contrasts with the concept of being cheap and poor in quality. Thus, "tawdry" emerges as the appropriate word that encapsulates the definition of something that is both cheap and of poor quality.
