Before deciding on any fabric - there are certain points to be checked: Find out whether it has to be dry cleaned or whether it can be washed. Has it been preshrunk? Is it color fast? Is the grain straight and are the prints on straight grain?

All fabrics, after they have been loomed, are treated in various ways so that they will have special characteristics. They can be made moth proof, water repellent, crease resistant, fire proof, shrink proof, given insulating properties, and textured. Each of these processes have special process names and are labeled so for identification.

In addition to these materials there are also other materials used especially for shaping. They can be either woven or non woven. Shaping materials are used to give added support for correct fit and to add firmness and body to fashion details, as in tailored clothes and in bouffant fashions.
