Uniform tip: no piercing

Did you know?  Off duty on a military installation, military
members are prohibited from attaching, affixing or displaying objects,
jewelry or ornamentation to or through the ear, nose, tongue or any
exposed body part (includes visible through clothing).

Piercing of earlobes by women is allowed, but should not be extreme or
excessive.  The type and style of earrings worn by women on a
military installation should be conservative and kept within sensible
limits.

Failure to observe these mandatory provisions and prohibitions by
active duty Air Force members, USAFR members on active duty, inactive
duty for training and ANG members in Federal service is a violation of
Article 92, Uniform Code of Military Justice (UCMJ).  Reference
