Thanks @Lyn (and Basil). That shall be my riposte in future in response to the singing of "Bye bye baby".....
I have a big ancient hooded brown felt djellaba, which is great as it cuts out the wind and covers me entirely down to ankles....who knows what’s underneath! I have been known to be found still wearing it (and my pjs of course!) mid afternoon in the garden. Heaven knows what the neighbours think as they sit in front of their mirrors and do their make-up with this strange person next door.
