Am thinking about waiting until I get to London to buy rainboots and coat, as I think they will have a much better selection there than we have here. I'd like to get something I can keep for a long time, which will always remind me of my first trip there. Are there shops which specialize in foul weather attire? Or is my best bet a major department store? Either way, what shops do those of you familiar with the city recommend?
Many thanks in advance, as always.
