It's fairly common (except the scarf)
But maybe that's a good thing for you if so many people like the look.

I dunno. It's looks "OK" but honestly, to me it just looks like one of those costumes rich people throw together to show "HEY I'M RICH"

Well, it's ok.

The problem is that snarby is blue-black, black and red, and that black kat cowl is dark purple and green. The more recent shadow items aren't black and red, but that offset dark grey and black and blue-black kind of scheme which works alrightish with snarbolax and occasionally well with black kat cowl. Overall, it kind of works and they're all "close enough", but it still looks patched together in a bad way.

The crown of winter/crest of winter are cool items, but they don't fit very well into the colour scheme.. think of them as being like the red in snarbolax, but frosty themed instead. For your look to really work, you'd want for the red in snarbolax to match with the frosty theme from the crown of winter... and it just comes across as being forced.

Black kat is really a hard item to work into your outfits though, mostly because you need an armor that fits the dusky theme, and that leaves all of chaos and angelic armor and justifier and dread skelly and the new trunks/sarong and a few others, though you can try to force unmatching items into working via accessories.

So, something like this? Let's use ALL the colors.

Alas, that isn't a picture of my fine self, but a picture I snuck of another fine fellow. Though I am rather guilty myself of questionable choices.

Everyone has an opinion so keep that in mind. Personally, I don't like it. Common, colours don't match and I really don't like seeing scarves on the Kat Cowls since they already have scarves. The shadow wings and cat tail look great with the coat but I still think that a Shadow Helm would look better instead of the Cowl. So, not really a fan of that costume.

Edit: I might not respond.
