Thank you peeps, I spent the whole day on T'internet after reading this thread to find a decent but stylish long raincoat. Why are they so sacklike? I'm short and I think I'd look like a sack of spuds in them. What are those shoulder bits all about? I don't want to look more triangular than I already am.
Why when you put "coat" in the search engine, do you get "Jackets"? They are completely different things. Why do half the sites not give a decent description for their coats? I want to remove the collar as they irritate me enormously and I don't mind a hair wash! .
Anyway, in the end, I went for a waxed cotton 3/4 length jacket. I figured with a long pair of wellies it will keep me dry enough. My lovely fireman's boots are a bit heavy for long walks so I started a new search. OMG, the price of wellies!
