i had my wedding dress made by the lady who lived over the road - the house just had 'tailor and dress maker' painted on the side - any tailor or dress maker will make the outfits for you - we went in and browsed wedding catalogues, picked out some styles and skteched the combination dress that i wanted, then after maeasuring me she advised us how much material would be needed and we went off and bought it - it was ready with one fitting in between around 12 days later!
Cheap too! good luck!
