Have you ever wondered why the Dragon Queen doesn't rock a crown like Cersei? It's because Dani isn't the (current) ruler of Westeros. According to Clapton, "she now has this fantastic new chain we've created. I didn't want her to have a crown, I wanted her to have a chain." And she's not the only one to have noteworthy necklace details.
Now that Sansa has found herself, she joins the ranks of the most powerful women of Westeros. Since returning to Winterfell, the eldest Stark's wardrobe changed dramatically. Clapton explains the symbolism of behind the new Lady of Winterfell's dark looks and her connection to the feuding Queens sharing, "just a showing of strength among the women. She has the chain, she has the circle, she's bringing all that she's been through to her costume."
