Are they ok to bung in the washing machine? DS's didn't come with any washing instructions and he's never had a blazer before. He's never wore deodorant or smelled sweaty before, but after wearing the blazer for 4 days it stinks of BO [envy] <not envy. I'm guessing it's because it's got a polyester lining and the school have a stupid policy of not allowing the blazers to be taken off even though it's 27 degrees this week. I've bought him deodorant now and showed him how to use it, and hang his blazer up outside to air after school, but really want to be able to wash it. Anything else I should be doing?
