How do you insert Pant into a player or so?

pants = script.Parent.Pants:GetChildren()
shirts = script.Parent.shirts:GetChildren()
faces = script.Parent.Faces:GetChildren()
hairs = script.Parent.Hair:GetChildren()
maindummy = game.Workspace.Camera.Dummy_3D
dummy = script.Parent.Dummy
repeat wait() until maindummy and dummy and hairs and faces and shirts and pants

script.Parent["Pant Label"].Next.MouseButton1Click:connect(function()
    curSpawn = pants[math.random(1,#pants)]
    wait() --Let the Character fully load
    for _,v in pairs(maindummy:GetChildren()) do
            if v:IsA("Pants") then
                v:Destroy()
                curSpawn = maindummy
            end
        end
    for _,v in pairs(dummy:GetChildren()) do
        if v:IsA("Pants") then
            v:Destroy()
            curSpawn = dummy
        end
    end
end)

So I have this folder in my explorer that has like a lot of pants and I want it to random choose the one of it and copy and paste it into the player, how would I do that?
