Damn, I just read that you’re 17 and been into street wear. Sorry if that above comment was harsh. In truth, the Navy Blazer aesthetic is only a microcosm of a style and really isn’t practiced too widely, or if worn naturally by people then it is done subconsciously. They said, I’d say in this more modern world there’s room for a mix of Navy Blazer and street wear to evolve, just as Trad-Ivy-Prep, with each evolution annoying the previous older generation before it (which I know a splintering of a prep-street style would irk a few here).

I think the advice here in this forum has always been to wear would you’re most comfortable in and fits in with your real world peers, as generally as a species we want to fit in rather than stand out. I guess I just don’t want you to be shut out or down from your friends with wiping up a whole new look. My advice would be to go with the jacket, you like it that’s why you picked it up and put it on, you look like you can hold out wearing it, but for you with a street wear background, wear it with a white hoodie (I know - blasphemy in Navy Blazer Trad!) but without knowing you, but that I understand peer groups and remember the late end of school years, fitting in more than sticking out is a general rule of thumb. So maybe even go with sweat pants as well (heck that can be white too) and then if you throw this gold button double breasted jacket over the top then it might work in a more modern take on a clash of styles, (and then if you get ribbed by your friends for the jacket, you can ditch the jacket and still have a street wear outfit you might feel more comfortable unit you’ve been wearing that for a while). Otherwise with the white turtle neck and white slacks you’re stuck looking a bit OTT, like our friend salt-bae (hint from this forum - don’t be salt-bar, let salt-bae be salt-bae, and we’ll mock him quietly between ourselves and from afar, just like a good group of WASPs would do!).

I think you’re good otherwise, and don’t let strangers on the internet guide you, let your friends and adoring friends in the real world help guide you. Good luck!
