Okay we are having a small informal beach wedding. My fiance is wearing black ****ie shorts with short sleeve white button up shirt. I can't figure if the best man and groomsmen should wear kakhi colored ****ies or grey ****ies with white button shirt. Any suggestions????

I vote khaki. I think it'll look better than grey and will set your man apart from the rest of them more.

I agree Khaki too.
