My DP has had a hoodie for about 2 years now, he wears it pretty much every day - but he has never washed it! It's a limited edition Assassin's Creed hoodie so it will be hard to replace if damaged. I have managed to get hold of it for a week... should I wash it? He has said that I can if I really want to... and I do really want to, it smells funny... how should I wash it?
