There are a few ways to get the paramedic outfit in GTA 5. The first way is to simply purchase it from any clothing store in the game. The second way is to find it on one of the many pedestrians walking around Los Santos. The third way, and by far the most difficult, is to complete all of the paramedic missions. These missions are not easy, and will require a lot of time and effort to complete. However, once you do, you will be rewarded with the paramedic outfit as well as a significant amount of money.
