It is true that the efforts seem misguided given the low visibility of the chain mail. To put this in context, consider that I have wanted to build this costume for over six years, since my first significant exposure to Link in ~ 2004. My goal was to create as good a costume as was reasonable and one consistent with the character. While I could have constructed small chain mail segments and sewed them on, it would be inconsistent with the character; it would be cheating.
I also wanted to make as much of it myself as possible while maintaining consistency; defining the precise tradeoff between accuracy and making the equipment myself is difficult. I purchased the shield, sword, and several of the leather components, for example, because I didn't think I could make credible versions of them myself and because their costs were not unreasonable.
The quintessential armaments of Link are the
sword and shield. Given that Link has access to
hammerspace to store his goods, I eschewed the accessories like bow and arrow, boomerang, bombs, and so on.
I should point out that I now have a fully functional chain mail tunic that I can wear for any purposes I see fit, including subsequent costumes. The construction is sturdy; I expect that the shirt will last at least ten years if properly maintained. Since it is made of stainless steel, I do not anticipate much corrosion. The shirt is tailored to my body, so it will give me incentive to not change shape.
While authenticity, not attention, was my primary goal, it is surprising how many "attractive nubile women" have sought to feel the chain mail through my shirt.
