can't toggle mesh renderer visibility

Hi all, I've been trying to find a solution for this for almost 4 hours but still nothing. I have a character mesh which is made of multiple meshes (the hair, the shirt, the shorts). When the ChangeForm input is given, I need to turn off the shorts and shirt skinned Mesh Renderer. For some reason, I can turn it off but it won't turn on again. I also tried pacing the script in another gameobject, but still it doesn't work. using UnityEngine; using System.Collections;

 public class ToggleVisibility : MonoBehaviour
 {
 
     //VARS//
 
     private PlayerState _player;
     private InputManager _inputManager;
 
     public GameObject top;
     public GameObject shorts;
     private SkinnedMeshRenderer topMesh;
     private SkinnedMeshRenderer shortsMesh;
 
     public enum PlayerState
     {
         NormalForm,
         EtherealForm,
     }
 
     // Use this for initialization
     void Start()
     {
         _inputManager = FindObjectOfType<InputManager>();
         _inputManager.OnChangeForm += ChangeForm;
         _player = PlayerState.NormalForm;
         topMesh = top.GetComponent<SkinnedMeshRenderer>();
         shortsMesh = shorts.GetComponent<SkinnedMeshRenderer>();
     }
 
     private void ChangeForm()
     {
         switch (_player)
         {
             case PlayerState.NormalForm:
                 {
                     topMesh.enabled = false;
                     shortsMesh.enabled = false;
 
                     break;
                 }
             case PlayerState.EtherealForm:
                 {
 
                     topMesh.enabled = true;
                     shortsMesh.enabled = true;
                     Debug.Log("enabled mesh renderer");
 
                     break;
                 }
             default:
                 //if i'm here i'm dead so do nothing
                 break;
         }
 
     }
 
 }
