They have the most amazing collection of arms and armor at the Metropolitan Museum of Art. I haven't been there often, but stumbled upon the room during a recent visit. Can you imagine wearing one of these? Here is a brief description of the collection from their website:
The collection of armor, edged weapons, and firearms in The Metropolitan Museum of Art ranks with those of the other great armories of the world, in Vienna, Madrid, Dresden, and Paris. It consists of approximately 15,000 objects that range in date from about 400 B.C. to the nineteenth century. Though Western Europe and Japan are the regions most strongly represented.
