You have not seen Arthur like this, have you. In the first book, for some circumstances, he is not too dressed, so I showed him to you accordingly. But now...
Let's watch the heroic ship HMS Maria. Here Arthur was on board as a special guest, and at the same time he helped in his area. After one of the storms, his everyday clothes were not in the best shape, and the sailors gave him something from the supplies on board. Fortunately, the uniform of the British Navy has not changed much over the centuries x)) I do not know about you, but I really like to see him with the coat of arms on his shoulder. The bandage, by the way, should be a handkerchief around his neck, but Arthur is not a fan of "noose".
However, in good old Victorian London, things were completely different. There, whether you like it or not, you have to comply. On the streets of his city, the young doctor was a real dandy. However, under the gloomy severity accepted in society, he hid his manifestations of cheerful rebellion - these are vests, for example (the prototype was a real-life vest of the 17th, it seems, century, he is now in the museum).
