I bought a jacket yesterday with care instructions that say 'professional dry clean'. I bought in a charity shop for less than £4 so I'm prepared to risk washing it instead. It's an OK brand (Alex & Co) and made of 52% cotton / 23% polyester / 18% acrylic / 7% polyamide. The lining is acetate. The jacket has quite a soft handle so need to worry about losing the structure. Here it is on ebay (it's more fitted than that photo suggests).
Do you think washing it - carefully, by hand - will be OK? What's the worst that could happen?
