Cotton is a soft, breathable fabric that is often used for casual clothing. Silk is a luxurious fabric that is strong, shiny and smooth, making it perfect for upscale attire. Cashmere is a lightweight, soft material derived from the wool of cashmere goats. Alpaca is similar to cashmere, but comes from the wool of alpacas. Both are highly coveted for their softness and warmth. Whether you prefer linen and wool or one of these alternatives, there is a fabric perfect for any occasion.
