What's "old-fashioned" mean? Is there "young-fashioned" too?

"Old-fashioned" means a style that is no longer current. It aligns with past trends and styles. And no, there is no "young-fashioned," I can see why you'd think so, though! The antonym of "old-fashioned" would be "current," "fresh," "modern," or "new." Ex: Her dress is really old-fashioned. Ex: Your outfit is so fresh.
