Button dilemma

I need help with the buttons for this sweater.  All of these buttons are in my huge button stash thanks to iPad aunt.  I don’t really want to buy any but I’m not sure which (if any of these) would look the best.  And I want to wear this sweater on Sunday…

This last picture is the best one for the yarn colors.  I like the mustard ones but they might be too big.  The rhinestones look great though they might be too small.  I’m leaning towards the last ones.
