Open up a fashion magazine, turn on the TV, or scroll through social media, and you’ll find countless bits of advice for how to appear natty — that is, smart and fashionable. “Natty” was originally 18th-century slang that likely developed from the word “neat.” Personal style can vary all across the fashion spectrum, but “natty” will most likely describe a person or clothing on the more professional or preppy side. Perhaps it’s a tailored blazer paired with stylish jeans, or fun accessories added to normally sedate business attire.
