When a player clicks a text button their shirt will change and it will stay like that, please help?

So far this is what i got but it doesnt work

wait(1) player = game.Players.LocalPlayer 
button = script.Parent

button.MouseButton1Click:connect(function()
game.Players.Character.Shirt.ShirtTemplate = "rbxassetid://878636506"

end)

i am still stuck on trying to make it so the clothes save when you choose it unless to customize again
