I bought my prom dress in 2022 for £300 and I’m hoping to sell it on Depop or Vinted. I’ve never sold or brought anything second hand before so I have no idea how to sell it, when to sell it, what to expect and how much to sell it for. Ideally I’d like to at least get £220 for it. Any tips would be helpful. Should I wait till January? Kinda want to get it sold as soon as possible but I have no experience of doing this so I’m kinda overwhelmed haha.
