WHAT ABOUT SOCKS IN BOOT CAMP?
This is a question that recruiters get asked VERY frequently. The correct answer is to bring exactly what the Helmsman manual says to bring, nothing more, and nothing less.
With that being said, if you bring a few extra pairs of socks no one is going to kick you out of boot. Cotton crew socks are fine. Ensure that they are all white or all black.
Minor color in the toe or heals is fine. The worst case scenario is that you store the socks at Boot Camp with your civilian clothes.
BOXERS or BRIEFS?
It is a personal choice, What do you normally wear? Boxers or Briefs are both acceptable. The key is Color. Look for white Boxers or Briefs. A Google search will list multiple outlets for them.
