I've only bought a couple of things off there so maybe I'm being unreasonable but I bought a dress last week, clearly advertised as a size 10. It's arrived and is very obviously a size 16. I've contacted the seller, no apology just told me to return it. I have to cover the cost of postage. The vinted returns policy says buyer to cover the cost unless the seller agrees otherwise. I think given that it was her mistake she should cover it. All rather petty I know but quite frustrating.
