Frankly, I'd hope it was obvious that you can't match those top boots with the coat.
Now, take different hardware, instead of the dull-silvertone you've got there, and you've got a chance.
Better yet, take the dull-scuff purple leather from the first pair, then put it into the third with black accents, or leather-and-velvet for the fourth, and we're talking some serious business.
Isn't that much obvious, now, once you stop and think about it?
