Does any other bridal shop stock these dresses apart from Annabel Rose and Sharon Hoey??
I'm living in the North and there is a fab bridal shop called Bellfield Bridal (with Spa attached for lovely facials and massages, you could make a day of it!) just outside Banbridge who stock Jenny Packham. If you google the name the website comes straight up.
I'll be heading there in the next couple of weeks to try some of her dresses on. They have a full list of the designers they stock on the website.
