A stylish person is someone who has a bold sense of fashion, like a queen with flowing robes and gowns, or your friend who always wears the best-looking jeans.
Stylish can describe polite and elegant manners, or it can describe dressing with the current fashion trends, like you walked off the pages of a magazine. The word style makes up the bulk of stylish, and stylish people are in tune with all the latest styles of dress. The suffix ish- can mean “belonging to” and also “addicted to,” and stylish people sometimes do have an addiction to clothes.
