Is this script right ? For giving specific player a new shirt pants and hat ??

I have put this in a localscript inside the Starter GUI but it's not working what im trying to do is to choose one player and remove its clothes and hats and give it a new shirt pants and hat which would be different than others "I think there's something wrong with the hat selection part" help please and I'll give credit thanks

assets={}
    assets.Shirt{90415298,114883953,140974162,81050287,112047296,92448971} --Shirts
    assets.Pants{65160698,89224181,67492557 } 
    assets.Hats= game.Lighting.Hats:GetChildren() -- hats go in a model under lighting called Hats

player =  game.Players.LocalPlayer -- gets the player
a = player .Character:GetChildren() -- Gets parts used for cleaning

function Clear() -- Removes hats Character meshes shirts and pants also T-shirts
for xX = 1,#a do
    if a[xX].ClassName=="Hat" or a[xX].ClassName=="CharacterMesh" or a[xX].ClassName=="Shirt" or  a[xX].ClassName=="Pants" or a[xX].ClassName=="ShirtGraphic" then
        a[xX]:Destroy()

    elseif a[xX].ClassName=="Part" and a[xX].Name~="HumanoidRootPart" then a[xX].Transparency = 0 
     end
    end
  end

Clear() -- Cleans the player
wait()
Shirt = Instance.new("Shirt",player.Character) shirts.Name = "Shirts"
pants = Instance.new("Pants",player.Character) pants.Name = "Pants"
hat = assets.Hats[math.random(1,#assets.Hats)]:Clone()
Shirt.ShirtTemplate = "rbxassetid://" .. assets.Shirt[math.random(1,#assets.Shirt)]
pants.PantsTemplate = "rbxassetid://" .. assets.Pants[math.random(1,#assets.Pants)]
hat.Parent = player.Character
