Alternative Wedding Dresses

I am getting married for the second time and in my mind 40's. I fancy going different to the big white dress I had last time and am contemplating something tea dress style, in pale florals from chiffon or similar.


I am looking for suggestions of shops that might have non standard wedding dresses that I hopefully don't have to travel a million miles to. I am bang in the middle of the country, between Derby, Leicester, Nottingham and Birmingham.
Can anyone suggest anywhere to try?
Thanks
