Wearing a reflective vest, in general, is not likely to get you in trouble. In fact, reflective vests are often worn for safety reasons in various settings, such as construction sites, roadwork, or during outdoor activities like cycling or running, especially in low-light conditions.

However, there are a few scenarios where wearing a reflective vest could potentially cause issues:

Impersonation: If the vest resembles those worn by law enforcement, emergency services, or other authorized personnel, you might be accused of impersonating a public official, which is illegal in many places.

Unauthorized Use: In some areas, wearing a reflective vest that is indicative of a specific role (like a construction worker or traffic control officer) while not actually performing that role could be seen as misleading or inappropriate.

Local Regulations: Some locations may have specific laws regarding the use of safety gear, including how and when it can be worn. It’s a good idea to check local laws if you’re unsure.

Private Property: If you're on private property and the owner has restrictions about what clothing can be worn, you might need permission to wear a reflective vest.

In most cases, wearing a reflective vest should be safe and acceptable, particularly if it is done for personal safety reasons. Always ensure that you're following local laws and guidelines.
