Wearing awards and decorations is prohibited when it would imply endorsement of private interests, in discreditable circumstances, or with costumes and inappropriate attire. Restrictions may also apply to former members of the awarding organization.
Step-by-step explanation:
The wearing of awards and decorations is typically prohibited in certain instances. While specifics can vary depending on the country and the type of award, generally, wearing such decorations is not allowed when doing so would imply governmental or military endorsement of private interests or when involved in activities that may bring discredit upon the award. This includes circumstances such as political events, demonstrations, or activities that are not officially sanctioned where the adornment of these awards might suggest official participation or endorsement.
Additionally, awards and decorations should not be worn with costumes or civilian attire that is not appropriate for the dignity and respect of the award.
