This Christmas the only thing I want is a huge, cosy dressing gown. I need it to be thick and super warm, knee-length or longer, snuggly and have two large pockets. I plan to live in it while I'm on maternity leave, as well as wear it with a massive bump, so the bigger the better. It also needs to be machine washable too, so I think wool is out. Has anyone seen this marvel and could tell me where to buy it from please?
