The elasticity of knit fabrics, as opposed to woven fabrics, makes them more comfortable to sit in. Nylon, rayon, satin, acetates, silk and polished cotton are slippery making it easier to move in bed or get in and out a car. Don't choose fabrics, such as angora, that shed or tend to irritate. Generally, the more tightly woven a fabric, the more durable it is. Sturdy fabrics, like denim, wear well but don't stretch.
Some stretch is usually better.
Whenever possible, purchase garments that you can machine wash and dry. Dry cleaning is costly and requires trips to the cleaner, and hand washing requires time and energy. Select permanent press fabrics that wrinkle less. Clothing that fastens in the front is easier to manage, but avoid the open ended zippers found on many casual jackets. Vertical buttonholes and large buttons are easier to manipulate than small ones.
