I need a coat with a hood for walking with the pram (no hands free for an umbrella). I'd like something casual, but smart enough for lunch in a nice pub, that kind of thing - maybe a parka or something like that. I'm 5 feet 7 with long arms - I find the arms tricky (eg M&S are always too short in the arms). I'm a jeans-and-Converse kind of girl, size 12, and I'm 31. I'd prefer not to spend more than £100 if poss. Has anyone seen anything recently that might fit the bill?
