They play sisters Arya and Sansa Stark, respectively, on the hit HBO TV show, Game of Thrones. 

And Maisie Williams and Sophie Turner turned heads in their equally-stunning, yet contrasting, red carpet ensembles at the series’ six premiere in Los Angeles on Sunday.

Maisie, 18, showed off her playful side in a girly number, while Sophie ventured into mature territory with her floor-sweeping gown.

The bottom of her ensemble was a work of art. It featured a white, orange and yellow abstract design.

Her bra-like upper half coordinated with the rest, black fabric outlining the white-coloured fabric inside.
