Is all black too black?

I pretty much always knew I wanted the bridesmaids to be in black dresses, as green is not the most flattering of dress colors in my opinion.  Then, somewhere along the line we decided it would be cool for the groomsmen to wear all black suits (with the exception of green handkerchiefs)... I didn't even think about the fact that that leaves 11 of the 14 people at the altar in all black, and three in white and black (bride, groom, MOH).  My fiance is pretty set on his groomsmen wearing all black.  I think black and white is classy to an extent, but I don't want to look gothic, any thoughts?

Here is the lame looking picture generated on Davidsbridal.com (the MOH's top is supposed to be white, and these aren't any of the dresses or the right color of flowers, and the groomsmen will have kerchiefs, not boutonnieres.  The groom and groomsmen will also probably wear black and white checkered vans):
