I've seen images of this photograph for years on everything from greeting cards to t-shirts. At first glance these ladies do indeed look like a coven of witches, but fear not and put the kettle on, tea friends. They are nothing more than a group of Welsh women dressed in traditional Welsh costume, invented in the 1830s by the very interesting and very Welsh Augusta Hall, Baroness Llanover of Monmouthshire. (Boy, did SHE ever need the services of "What Not To Wear"!!!)
If you do a Google image search Traditional Welsh Costume Tea you'll be treated to hundreds of great photographs and yes, they all look very "witchy"!
Nevertheless, it's a great Halloween pic, isn't it?!
