interesting. as you had suggested that jodphurs would be out of place with a suit, but they are so similar to chelseas. just figuring out the nuances.
Jod boots are pretty much paddock boots, which is for riding horses and everyday wear. They are more casual and have ornaments (buckle). The more going on a piece of footwear has the less formal it is. A jod boot with a suit is too much.
