Oh. Oh, God.
So what in the hell could possibly be the innocent context behind this? Well apparently "Nazi Chic" has taken Asia by storm, to the point where the Chinese couple above felt no shame in using an SS uniform for their ceremony. The original blog post, published in 2011, is entitled "My SS military uniform and bridal veil~Everybody, be nice now~(^o^)/~." And as everyone knows, cutesy emoticons automatically negate judgment for romanticizing the most hated symbol of all time.
While no one seems to know exactly who this couple is or why in the sweet name of God they're dressed like this, most "Nazi Chic" cosplayers insist that they're not in any way Nazi sympathizers but rather Nazi fashion emulators, a distinction that gives no one anywhere any sense of comfort or relief.
