Annoying brother, help

So my older brother keeps on telling me what to wear, because I like to wear the same shirt over and over again. but when I say over and over again, I mean like 3 times in like, a month. and its really annoying! I know he’s trying to not make a fool of myself, but really, I feel comfortable, and plus, a couple of my cousins wear the exact same shirt more than 3 times in a row, and my mum too! and he doesn’t complain about that! but he complains about me! and just now, my brother was like “the next time we go out, if you still wear the same thing, im going to throw out your other clothes” I mean, come on. god. these things just makes me wanna tear off his head. REALLY! another reason, is because some of my clothes dont fit me well, but it looks good to my mum and bro. and if I say theyre too tight or something, he’ll be “well then, dont eat too much!” seriously, they have some kind of problem or something? if I try to eat healthy, I get make fun of. if I workout, same thing. when I dont eat that much, they tell me to eat a lot, and force me even when im full. I mean, I WOULD definitely answer them and tell them all this, but that would be ‘rude’ and I’ll get scolded and sht. and we wont joke around or be as talkative as usual and all. fjrfiorigiibnip. advice or anything?
