What can i do to look older?

i think that getting a tattoo is a good idea except for the fact that you would have it for the rest of your life :/ but i would not go to the extremes of dying your hair a colour that isnt usual cuz that could make you look even younger, but i think maybe you should try getting a different hair cut, or growing facial hair. my boyfriend looks like hes younger without his facial hair so maybe that would work.
