Kanchivaram Sarees

Im going to my cousins wedding to be held abroad, and I need to get a sari for her. I really want one with an embroidered border (diamonds, glitter and wire-working), but preferably I'd like it to be a sari silk georgette or rather than anything else.
I really need to know of any shops in London or at least in England that sell silk sarees by South Indian saris example (Kanchivaram) suit for a wedding, I only know 2 and IM does not range available.

Thank you!
