Got invited to a coast guard ball- no idea what I'm doing 😂

sooo a really cute guy I've been talking to goes to the coast guard academy and invited me to the ball!! I've obvi never been to a military ball so I have absolutely no idea what to expect. I know what to wear but aside from that that's it! I'm also worried because I feel like I don't know him that well yet so the whole thing is making me kinda anxious even though I'm excited 😂 any tips would be much appreciated💓🇺🇸
