I have just bought this dress from Zara www.zara.com/uk/en/woman/dresses/combined-chiffon-dress-c358003p1870516.html (apologies for link - on phone). I love it but I've just realised that it's dry clean only. It is 70% viscose and 30% wool - do you think it's possible to hand wash? I know it'll end up in a heap on my bedroom floor if it has to be dry cleaned so I'll have to take it back
