You buy a shoes and a pair of jeans.

want or need?

depends on your situation but it's a want unless you need clothes because you don't have any.

Explanation:

Need.

These both protect people from cold and water (at least a little.) Shoes protect feet, jeans protect legs.

Hope this helps and have a nice day.
