my top sites for secondhand shopping!!! i am truly obsessed with them, it is like hunting for treasure. i also like browsing depop, etsy, and vestiare, though i only have a handful of items from those in my wardrobe. i hear good things about vinted and medium things about grailed but i havent spent any time w those. i dont really use poshmark but it is massive. also check out the app called gem, it will check all these sites and more to find any keywords that you enter and email you a list of new items matching your query!
