Which adjective describes someone who is neatly or smartly dressed?

The term "natty" specifically refers to someone who is stylishly dressed, showing a keen sense of fashion and neatness in their appearance. Typically, it conveys a sense of sophistication and care in one’s attire. This is distinct from the other options, as they either imply a lack of neatness or an informal style. For example, "slovenly" describes a person who is untidy or unkempt, while "disheveled" similarly conveys a disorderly or messy appearance. On the other hand, "casual" refers to a relaxed or informal style of dress, which does not align with the idea of being neatly or smartly dressed. Therefore, "natty" is the most fitting choice in this context.
