questions about society

Short story. Don’t understand this society much. How do boys want girls to dress? Do they care if they wear crop tops or if all they wear is hoodies and sweatpants. I don’t know how I should dress. If you dress simple people say that you’re poor. If you dress nicely people say you show off. People are always judging us and people are always going to judge us. I don’t know if I want to paint my nails because I worry what others will care. I don’t know if I should defend my style and dress how I want or if I should dress simple. I don’t want if I want to wear a dress when I graduate or if I want to celebrate. Because I can’t think of anything I should celebrate about because the last 2 years haven’t been easy for me. While some girls will get their nails done and wear dresses I don’t want to. I don’t want to look good after everything I’ve felt and been through. I also have so many questions if boys should know about periods at this age I know the boys in my school are friends with girls. But I don’t know if they are aware of menstruation and I’m sure they’re aware. But as a girl myself I hide my period and don’t wear grab a makeup bags for my pads because I feel they might notice. Because as a boy if you see a girl with a makeup bag or a pouch going to the bathroom and you don’t see her comeback with makeup on. So yeah so many questions about society and so much has happened to me.
