It is a good idea I think.
Maybe have a sell and a borrow. If you have a friend that hasn't got a particular outfit then you could lend it to them for say……..what? 24 hours, maybe less, to see if they like it or not.
I have certain pieces of clothing that I'll never wear. Selling them would be better than them clogging up my wardrobe, especially if you have a lot of clothing. It's hard to find what you want at the best of times. Getting rid of some would help.
Just a thought. I know someone I have talked to recently suggested gifting clothes. Think they mentioned it a long time ago in here too. But, I suppose what would help all of us not buying clothes we don't like after we buy them is a changing room, were we can actually see what we look like before we buy them.
