I'm looking at the 2022-2023 female packing list and it says "white cotton briefs" - how do folks know that other colors are allowed? Also must they be those high rise briefs? My DS wears normal low rise bikini and they are typically a cotten, poly spandex mix. Also I don't see anything about compression shorts on the packing list, am I looking at the wrong list? I know the USAF is pretty different culturally but my spouse is a Marine and when they give you a packing list, they mean you should get exactly what they say, not what you'd like - otherwise you are dressed down pretty aggressively.
