Item Equipped Upon Entrance?

I've been trying for the past few hours, and I cannot seem to come up with a script that allows me to add a model to my character upon entrance of the game, such as a cape or model backpack. I don't know if any of you remember the Roman Parthia, but upon entrance you'd be forced to wear a Tanned Tunic as a starter item and I'm looking to do this but only having the model equipped to you if you are in the specified group.

game.Players.PlayerAdded:connect(function(player)
    repeat wait()until player.Character
    local ModelId=144776710
    if player.Name=="Vhaeron"then
        ModelId=144776710
    end
    local ModelId = game:service("InsertService"):LoadAsset(ModelId):GetChildren()[1]
    ModelId.Parent=player.Character
end)

Well, if you want models then you will need to call a weld script when

game.Workspace.ChildAdded:connect(function(AddedItem)
	if AddedItem:GetPlayerFromCharacter() then
	--Weld
	else
end

You can also modify that by doing

plr =  AddedItem:GetPlayerFromCharacter()
if plr and plr:IsInGroup(GroupId) then
	--Weld

As for tools, you could modify it by getting the humanoid and using :ForceEquip()

Hope this helps.
