ooh, simply be. I'll look there. I tried M&S and evan but I didn't see anything waterproof. What's the difference between water resistant and water repellent? I took them both to mean "Great for walking from your car to a building and back but anything more than a few blocks and you'll be soggy."
I was looking at gooutdoors but the first coat I saw that I really liked, I checked against the manufacture's webpage and they said they only make up to a size 18

But I guess it falls into the "easily returnable" catagory

I saw a little plastic, folds into a pocket rain coat that fits, if snuggly so I can probably get that in a pinch (it's only £15) to keep me dry while the search continues. I just don't want to spend the money on a stopgap and then have to spend another £150-200 on the real deal.
