What are some less-cliche, non-creepy but flirtatious compliments someone can give to a girl?

If I were a girl and some guy tried to flirt with me by telling me I had “beautiful eyes” or a great smile, I think I would throw up. Any less-cliche but still flattering compliments? Complimenting an article of clothing is already one idea, or perhaps thats too corny.

Girls? Anything?
