  Modify the TShirt class in the Drag2Shirts example to be more "fancy" by adding at least three additional graphical objects to its design. You might consider adding text, some buttons, a stripe or two, or anything else you might want. At least one should extend the "footprint" of the original shirt in some way. Note that you do not need to make any changes to Drag2Shirts.java to have both shirts displayed use your enhancements. Behold the power of object orientation!

  Please submit only the file TShirt.java in Submission Box under "InClass5" before you leave class.
