I honestly wouldn't go that far into peacocking your dress code. I would do what is comfortable. Dark jeans (tight, not skinny, well both count but I would NEVER be caught in skinny jeans, I like to have my balls).
Anyways, so dark jeans is fine, nice shoes - does not have to be dress shoes but as long as they are well kept, that is fine. According to girls I have talked to even, they can figure everything out about a man just by their shoes...
Just from a quick google search here is a "breakdown" i guess - not so sure how valid this person's article is though:

In regards to shirts, you can wear ties, shirts and blazers and that's all good. I did dress up with a dress shirt, a tie and a sweater vest and went to the pub ONLY because we were having a classy night later that night at my place - so I was ready for my night plans anyways.
Yes, I did get a lot of attention, because I stood out - the shot girls were even begging me to buy shots, it is still attention when they come from behind you, wrap their arms around you and shove their tits in your head, and you STILL get free shit when you dont buy a shot - note: I did not game, I did not know about the game then and I wish i did x_x
Anyways, I do have a nice dress coat I wear out when it is cold at night, that brings in attention. I wouldn't say dress the same every day / every weekend. This is college, you will see the same amount of people ALL 4 years with a few mixing in and out. My rule of thumb, if you look well kept, you are good.
My biggest peacocking thing, and I get compliments alllll the time cuz of it - I have an ascot hat (look it up if you don't know what it is) and omg does that grab the girls attention. I just need to perfect my irish / Scottish accent to fuck with them haha.
College rule tip: read Conquer Your Campus and learn early, unlike I did.
