/**
 * Class for storing various types of clothing;
 * @author mva021
 * 
 * This type of Object mainly stores information with brand, size and type being examples.
 * Such variables are called field variables or instance variables.
 * The collection of field variables is called the state of the Object
 * These variables all should have get methods, and could have set methods if you want to be able to change the property.
 * Brand typically don't change, unless you buy cheap clothing and replace the labels with proper brands in order to earn some extra bucks.
 * The important part of a State is those field variables that can change.
 * 
 * Which field variables can change in an object of this class?
