I’m a guy trying to rebuild my wardrobe on a tight budget — what are your best tips for looking good without spending a lot of money?

New user pass phrase: This community is for curiosity, not karma farming.

So l've never been interested in what I wear as long as it fit I was ok with it but now I really want to make more of an effort. I'm in my early 20's and want to start building out my wardrobe but don't want to spend a lot of money just for me to not end up liking certain styles or pieces a week from when I bought it. I don't think I have a style so any advice or suggestions as to how to figure that out would be cool too. This feels like something I should've had figured out back in high school so it's kind of embarrassing but I hope I can get some helpful advice from anyone here. Thanks in advance
