Hello, I have an oak Bayswater which I use as my everyday throw around bag, it's softened nicely over the last 12 months. It goes fine over my shoulder although I don't overpack it, it IS quite heavy but that's more because it can hold so much and there is a temptation to fill it, it might be a bit of a squash over a thick coat.
My only warning is it got caught in the rain on one of its first outings and it spotted badly, dreadful mess it looked, I was in a right state over it and contacted the company, I've not been able to do much about the marks (might be worth asking about a waterproof treatment when it is brand new) but now, the bag is a bit darker overall, the spots have blended in, it goes out in all weather and looks fine in a slightly distressed vintage-y way. I love the colour and wear it with black outfits etc, it goes well with every colour, a real workhorse.
