How do i become more girly?

im a tomboy and im about to b a high school senior. i really dont want to b remembered as a "she-hulk" or tough. i already hav a boyfriend and stuff like tat but i dont wanna b this version of me anymore. i want a more pink arua to me but i dont want to do it suddenly cuz people will call me a poser like the last day of school when i put makeup on (my pic is me on tat day). i just need suggestions on how to do this gradually and how not to feel awkward about it.
