rakish
Stylish and confident in a daring, slightly naughty way.
Rakish describes someone or something with a dashing, slightly disreputable charm. A person wearing a hat at a rakish angle has tilted it just so, giving off an air of confidence and adventure, like a swashbuckling hero in an old movie. The word suggests someone who's bold, stylish, and maybe doesn't follow all the rules.
A rakish smile might be a bit mischievous, hinting that the person smiling has gotten into some harmless trouble or is planning something clever. A ship described as rakish has sleek, swift lines that make it look fast and exciting, built for adventure rather than plodding reliability.
Today, when we call someone rakish, we usually mean they have that appealing combination of confidence, style, and a hint of rebelliousness. Think of a character in a story who shows up looking cool and collected, ready for anything, with just enough mystery to keep things interesting. There's always something slightly daring about a rakish person or style.
