How to make a button that when you click all hats get remove ?

title says it all, ik this is not a request site but i tried my best and i could not do it

This is technically made a fixed version of what blowup999 typed in his answer. Click here to learn about GetAccessories. Click here to see about Instance.new (Using the second argument in Instance.new is bad practice and takes a lot of computer power for it to work), even the wiki says that you shouldn't use the second argument when using the Instance.new. Plus I simplified the UserInputService event to a simple MouseButton1Click event.

local plr = game.Players.LocalPlayer
local char = plr.Character
local hum = char:WaitForChild("Humanoid")
local tb = Instance.new("TextButton")
tb.Parent = plr:WaitForChild("PlayerGui") 

tb.MouseButton1Click:Connect(function()
    for _,v in pairs(hum:GetAccessories()) do
          v:Destroy()
     end
end)

Should be in a localscript, tell me if it doesn't work and read about UserInputService for how it tells when click started

local plr = game.Players.LocalPlayer
local tb = Instance.new("TextButton", plr.PlayerGui)

tb.InputBegan:Connect(function(key)
	if key.UserInputType == Enum.UserInputType.MouseButton1 then
		for i,v in pairs(plr.Character:GetChildren()) do
			if v:IsA("Accessory) then
				v:Destroy()
			end
		end
	end
end)
