How to change the player look when the player enter the game?

I wanna change the player look to look like a noob but I don't know how.Can someone help me?

First, when the player join, use the function PlayerAdded so we know that a player joined.

game.Players.PlayerAdded:connect(function(plr)
end)

The player will be called plr

We don't have the Player's character?! So we must wait for it. Use the function :WaitForDataReady() so we know that the player has loaded.

local Character = plr:WaitForDataReady()

But we still want to remove hats, shirts and pants?

The function :GetChildren() will get every children of the Player's character.

local Children = Character:GetChildren()

Now we have everything, we must sort out the children, the ones we delete and the ones we keep.

for _, Object in pairs (Children) do
if Object:IsA("Shirt") then
Object:Destroy()
elseif Object:IsA("Shirt Graphic") then
Object:Destroy()
elseif Object:IsA("Pants") then
Object:Destroy()
elseif Object:IsA("Hat") then
Object:Destroy()
end
end

if Character.Head:FindFirstChild("roblox") then
Character.Head.roblox:Destroy()
end

All the unwanted stuff like the shirt, the t-shirt, the pant and the hats will be destroyed.

But now, we still need to change the player's character's colors to noob's colors.

if Character:FindFirstChild("Body Colors") then -- We check if it's here
Character["Body Colors"].HeadColor = BrickColor.new("New Yeller")
Character["Body Colors"].LeftArmColor = BrickColor.new("New Yeller")
Character["Body Colors"].RightArmColor = BrickColor.new("New Yeller")
Character["Body Colors"].LeftLegColor = BrickColor.new("Bright green")
Character["Body Colors"].RightLegColor = BrickColor.new("Bright green")
Character["Body Colors"].Torso = BrickColor.new("Bright blue")
end

Everything should work fine, if you have a question ask me! Hope you understand how it works. Entire Code:

game.Players.PlayerAdded:connect(function(plr)
local Character = plr:WaitForDataReady()
local Children = Character:GetChildren()

for _, Object in pairs (Children) do
if Object:IsA("Shirt") then
Object:Destroy()
elseif Object:IsA("Shirt Graphic") then
Object:Destroy()
elseif Object:IsA("Pants") then
Object:Destroy()
elseif Object:IsA("Hat") then
Object:Destroy()
end
end

if Character.Head:FindFirstChild("roblox") then
Character.Head.roblox:Destroy()
end

if Character:FindFirstChild("Body Colors") then -- We check if it's here
Character["Body Colors"].HeadColor = BrickColor.new("New Yeller")
Character["Body Colors"].LeftArmColor = BrickColor.new("New Yeller")
Character["Body Colors"].RightArmColor = BrickColor.new("New Yeller")
Character["Body Colors"].LeftLegColor = BrickColor.new("Bright green")
Character["Body Colors"].RightLegColor = BrickColor.new("Bright green")
Character["Body Colors"].Torso = BrickColor.new("Bright blue")
end

end)
