I live at the coast in Northern Ireland and have dogs which require at least 2 daily walks 365 days a year. I'm an 'outdoor' (as in outdoorsy/not dressy) coat obsessive, I collect them and have waterproof and/or insulated coats from Arc'teryx, Patagonia, Paramo, Schoffel, Fjallraven and Helly Hansen, but I still wouldn't be without my Dryrobe. I wouldn't wear it on a long walk or for hiking or anything, but on a miserable January morning when the rain is blowing sideways and I don't have loads of time and just want to get the dogs out for a half hour run, I can throw the Dryrobe on over whatever I'm wearing and stay completely dry and warm. It's a brilliant dog walking coat, the hood is great and it has massive zip pockets, they really are incredibly practical. We rarely meet anyone else at the places we walk on days like that but I don't give a shit what it looks like anyway. I don't wear it out shopping or anything but absolutely tons of people around here do and nobody bats an eye. Honestly, go for it,
The other one I'd recommend if you want a really waterproof and warm big parka type thing would be Helly Hansen, but they're a lot more expensive and not exactly high fashion either.
