The title--Wedding in Blue--reminds me just how many monochromatics blue actually has. If your bridesmaids are going for blue, consider letting them dress them in various necklines, waistlines, etc., complimentary to each particular to each individual body type. And if you still don't like the-everybody-in-midnight-blue thing, try graduated shades of blue instead. Also think about accents. Blue can be worn as florals, sashes and belts, and for the guys pocket silks and ties.
