The present Mrs Jenks favours fur/fake fur hats when the weather is anything but hot!

She also has a1920s style linen hat from "Peak and Brim" for the summer, rather like this one.....

I did suggest the idea of a flying helmet.... I will not write her reply in a public place, but it did involve a stick of wet celery as well as the flying helmet .....and I wouldn't enjoy it.
