When describing someone or something as "decent-looking," there are many other synonyms that can be used to convey the same meaning. For instance, the phrase "good-looking" is a common alternative that is often used interchangeably. Other options include "attractive," "appealing," "pleasant-looking," "handsome," and "pretty." Each word has a slightly different connotation and can be used depending on the context. "Attractive" and "handsome," for example, may be more appropriate when describing an individual's physical appearance, while "pleasant-looking" and "pretty" may be better suited for describing an object or scenery. Ultimately, the most important thing is to choose the word that best captures the desired tone and meaning.
