advice for high school?

so i’m new to high school, and i’m very insecure. i have huge boobs and like no ass so i feel like my body is very weird. everyone is so judgmental and they judge everyone else’s bodies. tomorrow is the day that we’re supposed to wear pajamas and i wanna use that as an excuse to dress comfortably and wear sweatpants but obviously sweatpants don’t make my ass look good. i’m like, i shouldn’t wear sweatpants because i’m gonna look bad but yet at the same time i’m like, it’s pajama day, and it’s sweatpants, no one expects anyone to have an amazing looking ass in sweatpants and its comfortable. what should i do 🤦‍♀️
