So, “look” is just a trendy word that is often used when talking about a person's style or outfit. It's a way to describe how you are dressed today. For example, if you are wearing jeans, a t-shirt, and sneakers, then that is your “look” for the day.
The slang “look” came to us from the English language, where the word “look” means “appearance.” When people say “look,” they mean the entire set of clothing, accessories, shoes, and even hairstyle. The word became popular thanks to fashion bloggers and influencers who share their outfits on social media.
