Answer:
Harry must buy things that will protect him from the cold, such as a good coat, socks, gloves, a hat and a scarf to protect his neck.
Explanation:
Harry lived in a place with tropical climate, so we can imagine that Harry wore light and not warm, as it lived in a warm climate. However, Harry will move to a continental climate, totally different from the hot weather Harry is used to. Harry probably does not have clothes suitable for cold weather, so he will need to buy clothes and utensils to protect him from the cold. That way Harry will need to buy: a good coat, socks, gloves, a hat and a scarf to protect his neck.
