What to wear for family Christmas photos?

I am determined that we are going to do family photos this year to put in our Christmas cards. I don't think we've done them for the past two years. It will be me, DH, 13 yo DS and 9 yo DS. I struggle every time on what we should wear! I don't want us to be totally matchy-matchy but I know the colors should somewhat match with each other. I think in the last photo we did, 2 of us wore white long-sleeved shirts, and the other 2, red long-sleeved shirts and it came out pretty well.

Any ideas? What do you all usually wear?

Thanks!
