Which word is a synonym for garish?

The word "garish" refers to something that is excessively bright, colorful, or showy in a way that is considered tasteless or vulgar. A synonym captures the essence or meaning of the original word. In this case, "vulgar" fits because it denotes something that lacks refinement, sophistication, or is offensive in taste – attributes that align well with the connotations of "garish."

The other options do not capture the meaning of "garish" effectively. "Modest" and "subdued" suggest understated or restrained qualities, which are opposite to what "garish" implies. "Chic," on the other hand, relates to stylishness or elegance, which again contrasts with the gaudy or crude nature of something described as "garish." Therefore, "vulgar" is the most fitting synonym.
