Wow! Wisdom of the YLF hive mind! Thank you so much for all the tips. Lots to think on here.
catty: thanks for the lowdown on Poshmark. I really appreciate the detail, particularly on the shipping costs. I'll take a closer look at how it compares with the other platforms.
Diana: I'm thinking eBay could be a good option for things like English shoes, which don't feature so much on the high fashion radar but have a strong cult following. Thanks for the tip on searching for selling histories - that will be very useful!
Kate: I like your thinking on detailed descriptions. Good to know about shoes and toppers moving on eBay. I'll definitely look into that side of things a bit further.
shevia: I have an account on Vestiare, but never did anything with it until yesterday, when I submitted something for sale to test out the process. Waiting to see what happens there. I hadn't heard of TheRealReal before, so I'll check them out too.
And Angie, that's what I've always done in the past, but I realised lately that I found it very hard to release certain items into the wild without knowing where they were bound for. Emotionally, I need to take this responsibility for my wardrobe pets. Don't ask me why.
And the extra cash for my shopping budget is a bonus, of course
