Which civilian attire is prohibited aboard due to the policy?

• A. High-visibility reflective vest
• B. Conservatively pressed clothing
• C. Plain t-shirts with no graphics
• D. Undershirts worn as outer garments

Answer: (D)

Civilian attire aboard should present a neat, professional appearance and, when required, meet safety standards. Undershirts worn as outer garments are prohibited because undershirts are base-layer clothing, not designed to be worn as outerwear. They tend to look casual and can fail to provide proper coverage or the professional appearance expected in the environment. In contrast, a high-visibility reflective vest is allowed when safety requires visibility, conservatively pressed clothing conveys a tidy appearance, and plain T-shirts with no graphics are simple and unobtrusive. So the prohibited choice is undershirts worn as outer garments.
