I am glad I didn't have the previous comissioning experience.
My recruiter and his superior (the comissioning officer) went out of their way to come to where I live (3 hrs from their office) to have a little ceremony with cake and icecream that my family was able to mention. My family has a military history, and I am the first of my generation to join the military--so it was something that meant a lot to them and me.
Regardless, I wore a conservative business suit and had my hair tied back (female).
