Ds is having an Evacuee day at school as part of their WW2 topic - they have to wear suitable costumes - so far I'm thinking long shorts, long socks,gas mask box, little suitcase and teddy (they are all walking to the local station as if being evacuated) - I was wondering if there's anything else I could add and where would I find a sleeveless pullover (apart from hacking the arms of an old school v neck jumper) ?
