Both characters are in uniform rather than their own fashion choice in the picture.
Klingons are also the race that read love poetry (granted, while having stuff chucked at them by their mate), so I don’t think looking a little snazzy is exactly un-Klingon. I mean, heck, Worf got someone pregnant on the holodeck while in uniform.
Yawn, looks way to fashion oriented
Klingons aught to be all leather and discipline and some good wholesome Sadomasochism
