Wrapped round the shoulders and fastened with a glittery brooch to keep it in place et voila! No need for any hassle or fuss. Warm, elegant, stylish and cosy. Yes, the multi-tasking shawl is everything you need, and want, in a cover-up.
For Scottish-winter use, I recommend wearing it over a couple of layers: vest top, jumper etc, and you can even stick a wee scarf round your neck if you'll be feeling the chill. Go for a small, discreet scarf though, because if you wear anything long/woolly/brightly coloured you'll end up being all scarfy-fringey-action and look like you're channelling the Mental Boho Look. And not in a good way.
If you're lucky enough to have a turban as wonderful as mine, you might as well stick that on with it, too.
