Idk ur style but u could try a button up shirt that's like plaid or a normal tshirt or a striped tshirt. You could also get a polo or golf tshirt tuck it in your pants and wear sperrys for a more preppy boat attire? Lol you could also prob wear a plain white or black tshirt with the baseball jacket. Ooh or you could wear a patterned tee and roll the sleeves a little. And in the winter you could wear a sweater with it. Dark colors work well with light jeans. As for shoes I would say converse, vans, and if u could pull it off sperrys. But I think it's cutest with converse. I'm a girl and I'm pretty sure it would look awesome with a thin material white or black tshirt, the baseball jacket you suggested and some converse :D

Hope I helped

since its quite pale you could contrast it with a darker top half, so a dark grey or black. Could be tshirt, short sleeve shirt (they're very summery) or whatever you have that you think looks good. remember, style is subjective

how about some bright red converse or vans? and a dark blue V neck.or a darker color band tee? since the jeans are light, you shouldn't wear a pastel or light colored shirt. but the jeans look hot.

I honestly don't know your style,but I think a white t-shirt,probably a bling bling if you like,or even a sweatshirt it could go and you could also wear white converse if you like,but just rock it in anyway you can

yes.
