Best place to sell unused bridesmaid dresses?

Hi everyone, I have 6 brand new (tags still on) bridesmaids dresses that I no longer need. They were from Coast so not mega expensive but I’d like to try and get some money back for them. Does anyone have any recommendations of the best place to advertise them? I’ve put them on gumtree just now as have sold furniture and tickets there before so I am an established seller so to speak. But I wondered if there are better places? Where would you all look if you were interested?


Just as I was about to post I realised there’s a for sale section on here - so I’ll post an add here but would still be really interested to hear folks recommendations!
Thanks Isobel
