Our wedding is going to be casual, and I even put for the guests to wear khakis and button-downs... but it will be the end of October, and I originally wanted my fiance to wear a suit or just khakis and something nice, but his parents insist that he wear a tux, so... I was hoping he would be ok with khaki or dark brown but he says they don't look good with his skin tone ... We are looking at a dark grey one, but do you think a black jacket with khaki pants would look ok? Also, our colors are fall, like cranberry, dark brown, orange and yellow, which is why I didn't like the black.
