Question

Weed Apparel on Army base?

Answer 1

Military bases often have a dress code for the public government buildings. These dress codes vary depending on the military base and sometimes can become even more strict if the base is being visited by a high-ranking government official. Often these dress codes are posted outside of the public building. Most of the time the dress code is about wearing pajamas or bathing suits, but they may also contain rules against wearing anything that promotes something that is considered illegal by base rules. Even though marijuana  is legal in some states, it's not in places run by the federal government - like military bases. Since the leggings "advertise" what is considered an illegal substance they could be considered against the dress code.

The best advice for what to wear on base is to only wear what you think would be appropriate at school. This is generally the best way to judge whether or not you're dressed appropriately for the public spaces.
