From Weldons’ 1940s So-Easy line, this “Ten-Second” Siren Wrap features a cozy hood and chic contrast binding:

Other So-Easy air raid patterns included a women’s two-way siren suit (no. 19), child’s hooded siren suit (no. 17), and girl’s hooded siren suit (no. 18).

The pattern tissue is printed with an advertisement for Dewhurst’s Sylko machine twist.

For knitters, Weldons also had a special knitting book called Quick-Change Siren Woollies (click to view an Etsy download):

These seem to be a sort of coat-dressing gown hybrid. Curious as to what fabrics are recommended?
I was hoping to find fabric recommendations myself, but these patterns don’t seem to include them. The instructions refer to the garment as a “braided wrap with attached or detachable hood”; yardage is for 54″ fabric and optional 36″ hood lining.
I never even though about such a thing! What an interesting piece of fashion history. Thank you for sharing. I love the Quick-Change Siren Woolies and of course, I always love your blog posts đŸ™‚
