Hi looking for recommendations for a warm and waterproof coat that might be possible to wear with a dress or a maxi skirt? We're off to Sweden at the end of October it's highly likely to rain and temp wise only be around 10 Celsius so definitely need something warm and waterproof but I'd quite like to wear a dress too! Also going be doing a bit of sightseeing so reasonably light weight too! Am I looking for the holy grail of coats??!
