This research aims to enrich the field of decorative designs for the T-shirts of youth clothes. Youth T-shirts have been chosen because they are essential apparel and one of the most important casualwear. T-shirts are probably the number one item sold across the world. Every tourist shop has many of them, worldwide. The decorative ideas have been inspired from some symbols of Coptic arts. This incorporates the cultural power of Coptic art as a vital starting point for new design ideas and development of products. However, the purpose of this research is to make our youth know something about the Coptic arts of Egypt, as a part of their history, and on the other hand for tourists as well. Youth are very suitable tools for spreading our new ideas where they are energetic and full of life. In this work, twenty-one designs are presented inspired from ten Coptic symbols. Five designs have been implemented in three different ways of printing and embroidery, i.e. there are fifteen models have been formed. An opinion poll has been occurred for two groups of youth, one is younger and the other is older, hence T-test has been applied. It is clarified that our designs are approved by the younger group than the older one. The results of this work can offer some good reasons for further investigations on the fashionable decorated designs for youth and tourists as well; in addition to the decoration education development.
