How do you feel wearing black? If you will feel elegant and sophisticated then try it. However if it makes you feel drained and funereal then avoid it. I don't wear black at all above my waist (one black funeral coat being an exception) as it's such an awful colour on me, however, I appreciate some people really like black and wear it all the time. Could you get the same effect using brown? Or purple? If it was the outfit you liked rather than the colour just try a different colour.
