Welcome! When you say "basic training" - is this a military function?
Is it you who is graduating or are you the date?
Is there a MAC counter near you? If you're really super nervous you could book an appointment (at the dep't stores the $45 "fee" is actually a minimum purchase... so it's redeemable in MAC makeup... very good deal...)
Is there also a pic you can post?
it helps if we can see what you look like.
