Teacher Liu, I want to compliment people in a natural way, but I’m afraid it might sound awkward.

You can start with the overall look: “You look really nice today!” That sounds very natural.

What if I want it to sound a bit more refined?

You can compliment their vibe: “You have great presence. The more I look, the better you look.”

Is it okay to compliment details, like makeup or hair?

Of course: “This makeup suits you so well. It makes you look fresh and clean.”

What about a friend’s new hairstyle?

You can say: “This hairstyle is amazing on you! Your face shape looks even better.”

Can I use more internet-style expressions?

Sure: “You’re seriously blessed with good looks!” or “You’re illegally beautiful today.”
