Parents, dress casual. Hawaian shirts and tennies are fine. The order of the day for Navy OCS is that first your son or daughter with pass and review on the parade grounds, so you will be walking in the grass, just like a Officer and a Gentleman. Then, he/she will be commisioned in the base chapel. By now you will undoubtedly think its over, not yet this is the government, so he/she will get in line to render his/her first salute under the flag pole and give the token silver dollar. Phew is it over, not if their an aviation candidate, your son or daughter will proceed with orders in hand across the street to be checked in to API (Aviation Preflight Indoctrination). Its over, a long drawn out day for the sake of your son or daughter. Is it worth it? That's affirmative! So in the end dress light if its hot. By all means take pictures of all your family and get the DI involved. Don't be shy, this is your families day to be honored, you for raising someone with the fortitude to endure the last thirteen weeks and theirs for wearing that spiffy new uniform.
