It strikes me that women who opt for an arty all-black look are often craving a sophistication that color can "strip away," if you know what I mean. Color can draw attention to itself, after all!
This red is color like a painter uses it -- not as a woman seeking to decorate herself uses it. I don't know if I have quite the words to explain it, but this blood red, as you're wearing it here, seems deliberately chosen, as if it were part of a portrait in a gallery, rather than on a mannequin in a mall window.
Which means I love it on you!
