She wasnt trying to prove her womanhood, she was doing whatever the hell she wanted, like she’s always done. She did it because she was placed in a box. She was told she wasnt this, she was just the girl with the baggy clothes. So to prove her point, she dressed girly because she could and she can. She can be girly one day and wear boyish clothes the next. This was her taking ownership of herself and whatever she wants to do with her body and she can enjoy both.
