How to get the prices of accessories?

I'm trying to make a outfit calculator and I don't know what to use to calculate the prices. Here is how I want the code to look:

local Players = game.Players
Players.PlayerAdded:Connect(function(Plr)
	Plr.CharacterAdded:Connect(function(Character)
		local GetAccessories = Character:GetAccessories()
		-- Get Accessories Price.
		-- Calculate
		-- Print the value of all accessories
	end)
end)
