I wear the same outfits every week?

I wear the same outfits every week I have 2 sweat pants that dont go with anything els but 1 of my other sweat shirts but I dont wear that every week and I have 3 jeans and with the jeans I always wear 4 sweat shirts every WEEK!!!! Idk wat to do and I also have a T-shirt but I dont wanna wear that every week to and most of my sweat shirts r plad I have 3 plad sweat shirts one that is green and blue one that is brown and pink one that is purple and black the other ones are black adidas (I know I didnt spell it right) and the other one is black sweatshirt and thats all I wear to school for the whole year and a girl has teased me about it and I dont like being a tattle tale and I dont really thinks thats a reason to tell but yeah I do have this other sweatshirt but I have never wore it cus I think I saw one of my teachers wear it and I dont want to wear the sweat shirt when she wears it. Its like weird though for me every one kinda knows what I am gonna wear the next day but for other people u dont know. What should I do??
