My, my, my, I love that outfit! It describes Dany`s style perfectly : a little savage, a little oriental, with those brown boots who reminds me of the dothraki fashion and of course blue! I`ve simply fallen for it!
It`s totaly Missandei`s style, that oriental cut around the neck and the bright, dark blue. Plus the veils.
I believe it`s obvious why this belongs to Ellaria Sand: a lot of Orient, a lot of skin shown and, of course, a lot of orange.
And about this what can I say? It`s couture, elegance and exoticism in one simple dress. That embroidery around her chest and the decolletage, specific to Ellaria`s style made me consider this an Ellaria dress as well.
