I know it's a bit of a faux pas - or was in the past.
I'm attending a wedding and am struggling for an outfit. I tend to dress very casually most of the time. I do have a couple of summery dresses, one is very flattering and elegant - but it's black.
Is this still a no-go colour as a guest? I'm not a disgruntled MIL to be, or angry parent invited to a no children wedding.
