Eisenhower & George VI

[FatherWilliam57]

I, too, had never noticed this type of waistcoat before. (Gives me some new ideas about that clergy vest I need to have made...!)

Question: Does the waistcoat follow the line of the lower cut around the sides and back, or are these truly "flaps" in the front that frame the sporran? Since jackets are being worn in the pictures, I cannot tell.
