Thanks for brushing up the sentence. I want to know for future refernece when you find " adult look " or " adulty look " does it make sense? Or I should not use this term. Rather use " sophisticate" as you did.Create a sophisticated look by defining your eyes with brown eyeliner swept slightly upwards, and use black mascara for additional elegance.
Thank you! This will help me a lot!"Adult look" makes some kind of sense if you're addressing people who are not yet grown up, e.g. children who are "dressing up". But the word "adult" has come to have other (indecent) connotations that make any such use inappropriate. And there is no such word as "adulty". My advice would be to avoid using the word "adult" in the context of fashion and make-up, etc.
