A New Trend In Wedding Dresses?

Recently I've seen a lot of weddings where the bride pairs a black sash with her white dress.  Is this a winter thing?  A New Years wedding thing?

Here are two pics I saw on Facebook:

I saw this today on With This Ring:

Even the celebrities are doing it:

I think I'm too much of a traditionalist to appreciate this trend. I can see how some brides might like the idea of adding a modern, or even rock 'n roll element to their dress. I can see the New Years Eve, too, since black is a traditional NYE color.  Regardless of the reason, I'm not sure this is for me.

What do you think?
