looking up vintage/style name oftentimes pulls up overpriced resellers (LAME… end the depop industrial complex). but, if you look up the specific thing you’d like - e.g. “wool skirt” - you’ll likely find a lot more people listing that exact thing (including older more quality pieces) but with reasonable prices
(plus, it reduces overconsumption by making you think about if you actually need/want a specific thing or are just looking to buy random stuff)
