Hi Cari.
I agree - slowly but surely there are more shops springing up in the UK for the larger figure, but it's a slow process. However since being in Australia I can really appreciate how good we have it in the UK - there is no choice here at all! As far as bridal wear is concerned, I'd say it's the same here as in the UK from what I've heard - a bit hit and miss, you need to get lucky and find the right place. Easier said than done.
Have you chosen a dress yet Cari?
