The ‘very good condition’ is very wide ranging! Got a jumper this week, totally bobbled. I accepted it because it would have cost more to return it than the price. Seller of course didn’t show that part, straight in the charity bag.
I bought trousers, apparently ‘true to my size’, but when I tried it on, they’re 3 sizes too big. The label is xl, but they measured as a size 20. New owner gave good feedback. I think measuring is key, if the label isn’t ready obvious.
