the whole point of girls doing the not like other girls thing is basically them believing that the girls around them lack an interior life. they were raised on depictions of women as shallow caricatures and they recognize themselves to be actual people with thoughts and feelings, but instead of drawing the conclusion that these depictions of women are incorrect, they draw the conclusion that those depictions of women are correct and that must mean they're smarter and have more substance than the "average" woman. to exit the not like other girls phase means recognizing that all real life women have the same level of interiority as you do, and that depictions of women in the media as consistently empty headed and frivolous are misogynistic stereotypes not grounded in reality.
i say all this to say that to exit a not like other girls phase does not necessitate taking an interest in "traditionally feminine" ways of dress and makeup, nor does it mean never saying anything negative about the beauty industry
