For bigheads only

SIR – To be shaded from the sun recently I tried to buy a hat. All ladies’ hats now seem to be available in “size enormous” only, and fall off my head immediately when merely moving, never mind walking briskly or fighting a light breeze.

I discovered that several friends have the same problem. I bought two fairly pricey black squashy foam sausages to be held in place with Velcro but they kept falling out, being unable to cling on to the slippery lining band. Gill Rolls-willson
