Help with selection

Alright, so, I can equip multiple outfits, which I only want one to equip and the other one to de-equip with the color changing to the un-equip color. Basically only having one sloth to equip and not multiple.

Script:

local module = {} 
isEquipped = not isEquipped

function module:Init()
	local Uniform = game:GetService("ReplicatedStorage").Remotes.Uniform

	Uniform.OnServerEvent:Connect(function(Player, oldOutfit, ShirtId, PantId, Frame)
		local Character = Player.Character
			
		if isEquipped then
			Character.Shirt.ShirtTemplate = ShirtId
			Character.Pants.PantsTemplate = PantId
			print("Equipped uniform")

			Frame.BackgroundColor3 = Color3.fromRGB(85, 255, 0)
		else 	
			Character.Shirt.ShirtTemplate = oldOutfit[1] 
			Character.Pants.PantsTemplate = oldOutfit[2] 
			print("Default clothes equipped")

			Frame.BackgroundColor3 = Color3.fromRGB(90, 170, 215)
		end	

		isEquipped = not isEquipped
	end)
end

return module
