I’ve had decent luck selling on depop but it can be a lot of work to photograph and post everything and then packaging and shipping. I wouldn’t go into it thinking you’re going to make a ton of money, it‘s an ok way to make a little pocket money.
I’ve read a lot of horror stories on Reddit but never experienced being scammed irl (it helps to understand/be aware of potential scams though).
Just be honest about the condition of the clothes, sell your items at a fair price and don’t let people lowball you. If you have nicer items (designer or indie brands) try Noihsaf Bazaar for a chiller experience.
