Well there's no telling what dwarves will look like in Berserk. Don't expect them to be carbon-copies of Tolkien's. Personally, I have a feeling they'll be closer to the mythological representations commonly found in folklore. There's actually a panel showing the silhouettes of a group of elves different from piskies (elves like Puck) when Godot's cave is mentioned by SK that could be close to how Miura will depict dwarves in the future, but unfortunately I don't have it right now (I'll edit this post with it later on).
In any case, considering the armor's general size and looks but also its purpose and the way in which it functions, it does seem likely that it was created to be used by humans. Or do you mean that they only created one such armor? If so, that's also possible.
