I know it can be a bit pricey but they do have deals where you can get 3 pairs for about $20-30. They do have a variety of colors and fits and their size range is good. I feel like its worth the money bc they're made really well and are so comfortable :)
I like urban outfitters when they have good deals, and shopping secondhand mostly! hit up some thrift stores/consignment shops and maybe also get a pair of overalls🤷 get some jewelry, mix and match silver and gold if you can pull it off, and even styling the basics you have already. also, urban’s brand (bdg) has cool denim, i have a pair of green jeans from there :p
