Hello fellow Good Wardrobers

I have a couple of pictures of dresses that I have ripped out of magazines and kept in my diary for about 3 years now. I have decided it's finally time to do something about it and look into getting them made for me as I can never find anything I like as much. Can anyone recommend a good, inexpensive dress-maker / tailor in London / Buckinghamshire / Hertfordshire area? I figure word of mouth is better than just taking a punt on someone I find on Google...

Thanks!

Ellie
