Shirt + pants not deleting when they should?

First of all, I'm not on oder. Secondly, this script should've deleted the player's shirt and pants when they join (so that the body colors can be re-colored) but when I test this without wearing any clothing, it doesn't work.

if player.Character.className == "Shirt" == nil then
		print("There is no need to delete the shirt")
	else
		player.Character.Shirt:Destroy()
	end
	if player.Character.className == "Pants" == nil then
		print("There is no need to delete the pants")
	else
		player.Character.Shirt:Destroy()
	end

If anyone could tell why, that'd be great!

I'm pretty sure this works.

for index, child in pairs(player.Character:GetChildren()) do
	if child:IsA("Shirt") or child:IsA("Pants") then
		child:Destroy()
	end
end
