The vest and shirt:
I used Simplicity 4923 for the shirt and McCall's 2258 for the vest, with a few modifications. I sewed the shirt and vest by machine.
I used Butterick 3072 for the coat and Simplicity 4923 for the pants. I ordered the buttons for the coat from Jas Townsend & Son Inc. They are both sewn by machine. All the trim on the coat is sewn on by hand. I made the hat out of felt, using McCall's 2258.
