My fiance and I having been having discussions regarding the groomsmen attire. My fiance is wearing his dress uniform which is considered formal dress by the military. My son is the best man and is wearing his dress JROTC uniform. We are trying to figure out what attire we should put remaining two groomsmen in. The use of the military uniforms dictates a sense of formality (ie they should wear tuxs). The time of day however (ceremony is 11am followed immediately by lunch reception) dictates a more casual approach (such as vest and tie with no coat). Any ideas?
