Could anyone recommend somewhere to find a cool but functional parka-style coat? I'd like something hooded, oversized (rather than with a nipped waist) and reasonably waterproof in an interesting colour, as I have a small baby and am on maternity leave, and this will be my first autumn/winter spending a lot of time outdoors with a buggy/sling, rather than dressing more 'professionally.
Not khaki would be nice! Thanks in advance.
