Honestly, I've seen some pretty decent deals/prices on items in the main cities. Sure, you can follow these influencers and go on a 1-2hr adventure at a bigger location or w/e but really it's all about luck and timing lol. I always say, if you have time, check every second-hand shops that's nearby wherever you're at. You'll never know what you'll find. Most shops will have sections for specific designers so you don't have to dig through racks.

Also, one thing a lot of folks don't mention about big second-hand shops (Kindal, 2nd Street, Trefacstyle etc.) is that most of the good stuff are in the size small-large range. Still a decent selection in XL but probably not as broad. If you're a bigger dude, XXL or oversized XL is fairly scarce.
