An In-depth Analysis of the Costumes of Theon Greyjoy in ‘Game of Thrones’

The armors of the major families are all self-contained. We can recognize them at a glance.

The body of the Greyjoy armor Theon wears is in stone gray that fits the rocky landscape of Pyke Island. The exterior is riveted with a layer of brown leather, engraved with the Kraken from the Crest.

Theon wore Robb's red wedding dress at Sansa and Skinny's wedding(not the same style but the same dress, with the dire wolf buckles replaced with crossed straps) at Sansa and Ramsay Bolton's wedding. Sophie Turner, who played Sansa, confirmed why they did this was to increase the cruelty.
