jesus christ, this isn't that difficult.
if you want to wear a tie, that's fine, but you're going to stand out in a noticeable, and undesirable way. further, i have a feeling that the suits, sportcoats and ties you're choosing to wear -- based on your age -- are going to look like shit. i too am in college, and i work with a lot of students. i see hundreds of students a week. and none of them wear ties. they wear sweatpants, they wear jeans, they wear tshirts or button downs. they do not wear suits. they do not wear sportcoats.
further, just to preempt your inevitably reply -- i don't care that some people give you compliments. compliments are a horrible metric because most people dress like shit and have no knowledge of fashion. if you want lots of compliments in real life, don't look for advice, or approval, here.
I don't really see why you're getting snippy about it. I like to dress the way I like to dress. Any attention I get from it, be it positive or negative, doesn't bother me. Life's too short to worry about what some random, tenuous acquaintances in class think of how I dress, and it's certainly too short to worry about what people on the internet think of how I dress. If I dress a couple notches more formally than I should, well, I may as well focus on dressing as well as I can at that level of formality.
Side note: I find it confusing that you mention that college students all wear x as if to justify only wearing x as a college student, and then almost immediately follow that with "most people dress like shit." I wasn't going to bring up getting complimented again, but since you did, I also find it confusing that you say I'd stand out in an undesirable way -- which I'd imagine would be people thinking I dress badly -- but then say that the compliments I get -- which represent people thinking I dress well, not badly -- don't count. Would you be willing to clarify?
