Where and how do I get trashy y2k stuff

Hey, I've recently been getting into the trashy Y2K, Y2K bimbo, and the cigarette mom aesthetic or style. I know I could just go on Amazon or other online stores but I really enjoy irl shopping, ya know? Any tips would be helpful! Anything helps from diys or thrifting. Nails, clothes, decor, and accessories are the main stuff I'm looking for!

Im asking my relatives for small room decor like a blanket and other stuff lol.
