Joe Jonas knows Halloween is coming. And, he knows exactly where to look for a costume idea. 

The singer dressed up as fiancée Sophie Turner's "Game of Thrones" character, Sansa Stark, for Kate Hudson's annual Halloween extravaganza, presented by Amazon. 

Jonas captioned a pair of pics shared to Instagram "Saturday Nite" making good use of the jack-o'-lantern emoji.

To pull off the look, Jonas donned a fiery wig and floor-length, teal gown with bell sleeves and embroidery. (Turner herself went as an elephant.)
