If you happen to be Watch Climax OnlineKit Harington, what's the most embarrassing outfit you could wear to a Halloween party?

Well, there are probably a whole bunch of possibilities, but there's one costume idea in particular that blows all the others out of the water -- and it's something Harington actually hasdressed up as.

Harington shared all the glorious details in a recent interview with Heatmagazine, BuzzFeedreports. According to everyone's favourite White Walker-slayer, the costume was for a "bad taste" themed party -- and the idea for it came from Harington's fiancée and former Game of Thronesco-star, Rose Leslie.

"She pulled out a Jon Snow costume, and Rose just whispered in my ear, ‘I won't love you if you don't wear it... You should do it,'" said Harington.

That's right: a Jon Snow costume. And just to make things that little bit more perfect, the costume was apparently one of those all-in-one jobs you get from a Halloween shop.

“It was really embarrassing," Harington continued. "The people bringing around canapés were looking at me, thinking: 'You're sad, man! You've come to a party dressed as your character.'"

Tragically we don't have an image of the costume itself, but we imagine it looked something like this:

Well played, Leslie.

After seeing footage of the April Fools' prank Harington pulled on his partner earlier this year, he almost certainly deserved it.
