Given that the company have slapped their URL in the middle of the picture, I bet you could take a wild guess about who supplies this white plus size Pagan Wedding dress.
But URLs don't let you know their real world address, and it's remarkably fitting for the occasion.
Wedding and Bridal Boutique are based in Christchurch, Dorset, in England. The Wiccan historians amongst you will probably have their eyebrows halfway in their hairline by now, as that is the birthplace of modern Wicca. Gerald Gardner moved there in 1939. Amongst other strange encounters, he insinuated himself into the previously exclusive - and fading - New Forest coven.
The rest is history and the reason why you're looking for a Pagan plus size handfasting dress, as opposed to that of another religion/spiritual path. And yes, the shop does ship internationally.
As for other Pagan attributes, this Wiccan plus size Bridal Wear is white - the color of the Maiden. That makes it particularly perfect for handfastings held at waxing moon, or in the Spring months. Or for a Wiccan Bride who is young (at heart if not years), full of energy and/or embarking on this handfasting as a bright new beginning.
What it's not fabulous for is traipsing out into a field or halfway up a hill. White shows up the mud and dust terribly, and us Wiccans do love to get handfast in the middle of nature. Compare terrain to the handfasting gown and see what you think.
Though not pictured, there's much talk in the write up on the page about a colored train. Might I suggest red or burgundy? You're incorporating the hues of the Mother there. A touch of pink would also work, as in the dresses below, which are both available for Pagan brides in plus sizes.
