To record your study garment,  take photographs of the garment from all sides, INCLUDING THE INSIDE, with close up details, if your camera permits this. Send in the photos for processing.  If you do not have access to a scanner or digital camera, check the option of having your photos scanned to disk by the processor.  

Read postings on the Message Board about your garment.  The instructor  Tara Maginnis (and hopefully your fellow students) will give you hints about where to do searches for information on garments similar to yours.  Start looking for information that will add to a final report on your study garment.
