Twilight Princess Magic Armour
Twilight Princess Zelda
They look quite similar, don't they? The pauldrons, the gems on the pauldrons, the crest on the flap of fabric below the waist, the leaf crown. The resemblance is notable, so maybe Zelda's armour is Magic Armour? I'd imagine Zelda's boots and leggings are similar under the dress.
