Dapper means neatly and stylishly dressed, with careful attention to looking sharp and put-together. When someone is dapper, every detail of their appearance is just right: their clothes fit well, their shoes are polished, and everything matches perfectly.

The word usually describes men and boys, though it can apply to anyone who dresses with particular care and flair. A dapper gentleman at a wedding might wear a perfectly pressed suit, a crisp pocket square, and shined shoes. A dapper young man heading to a school dance makes sure his tie is straight and his hair is combed just so.

Being dapper means taking pride in your appearance and showing it through careful grooming and style choices. Someone dapper looks confident and polished without seeming stuffy or uncomfortable. Think of it as the sweet spot between too casual and overdressed.

The word carries a cheerful, admiring tone. When you call someone dapper, you're complimenting not just their clothes but their whole sense of style and the effort they put into looking their best.
