Why does my code say that 'Shirt' Isnt a valid member of player when my script checks if it exists?

I have a script that checks that if a shirt exists in my player character and then removes it but it always says that 'Shirt is not a valid member of Model "Workspace.EiOooAxea" '

Code:

if not char.Shirt then

else
	char.Shirt:Destroy()
end
