From Weldons’ wartime So-Easy line, an air raid suit for toddlers. One child appears to be carrying a gas mask case.
Other siren suit patterns were available for children, girls, and women, plus a “ten-second” siren wrap.

hey, that ‘back vent’ looks like a feature that should be incorporated into modern day adult female jumpsuits. lol!!!
This is so cute, and kind of disturbing at the same time. Thank you for sharing! I totally agree with jamaicaport about the back of the jumpsuit! 🙂
This is so sad. I suspect the drop seat was a necessity given the circumstances. It was so wonderful that most British children were sent to the country to live and were provided with vitamins. My mother, as an older teenager, worked for the war effort, but her sister was sent to the country from London. They both said they would be sent home from school if they forgot their gas masks.
