The assignment on Edg states:

-"Some fashion designers create sketches by hand while many use computer-aided design programs (CADs). Another benefit of STEM, CAD programs allow designers to view their designs on virtual models. They can also view different shapes, designs, and colors all from their computers. In general, it takes about six months for the complete design process, from initial design to final product. Besides selling their designs in stores, many fashion designers use e-commerce and the Internet to sell their products."

-"Outlast Adaptive Comfort products create temperature-regulating textiles. Outlast technology uses phase change materials (PCM) that collect and store excess heat from the body. When the body cools, the material then releases heat back to the body for optimal thermal comfort. This material can be incorporated into fibers and fabrics. With a material such as that, heavy coats and winter-wear clothing may not be needed!"
