I live in charity shops! We have a very good one near me, but I think few people are going to give away a good quality wool or cotton cardigan with plenty of wear! I can’t wear wool next to my skin, but a layer underneath solves that
Natural fabrics are going to be expensive, by their very nature. They are costly to produce unlike manmade fibres. Have you tried charity shops? There are also some ‘preloved’ cashmere websites and House of Bruar often have sale items.
Am I being unreasonable to be irritated by how difficult to find natural fabrics such as wool and cotton which are not mixed with polyester, which I hate and which irritates my skin. Woolovers are good, but expensive. In addition the added man made fabric adds to the unacceptable amount of clothing landfill in third world countries which is a growing problem.
