The best answer you're going to get is: it depends. Different communities are going to do it differently, and even the same squadrons in the same Wing will do it differently. Even the same squadron may have different policies throughout your tour. I'd roll with the Bates initially until you get a feel for your fleet squadron. You'll wear khakis off and on during flight school, but it's not anywhere near an everyday thing.
By the way, after I left my first sea tour, I can count the number of times I've worn my khakis on both hands. My current tour ruined my ability to be able to count it on one hand, but I'm still pretty happy with my track record.
