Polyester can be finished much softer than silk, silk can be a little rough hand feeling than the polyester. It depends on the fabric finishing. <br/> <br/> All Oscar Rossa silk has extra anti-split finishing procedure during fabric processing. This special procedure will make the delicate silk fabric more strong to use although it may compromise a little bit on the softness. In the meantime, the silk fabric was processed as soft as possible. <br/> <br/> Benefit of Silk: Silk is the most hypoallergenic of all fabrics because of its natural protein structure. It contains natural protein and 18 essential amino acids including cellular albumen which helps speed up skin cell metabolism. Silk proves beneficial to those with sensitive skin conditions. Silk is a natural temperature regulator, it helps the body retain heat in cold weather and expel excess heat in warm weather. <br/> <br/>
