It is not accurate to judge whether a fabric is silk or polyester only by hand feeling. Polyester can be finished softer than silk; silk can be a little rough compared to the polyester. It depends on the fabric finishing. Customer is encouraged to google to find out how to check it is real silk. · Silk is very delicate fabric, not comparable to cotton or polyester in strength. If it is made too soft during production, the delicate silk fabric will be much easier to incur ripples or even split during long time use if the wearer keeps on pulling it especially in the areas of armholes and crotches. So, silk should NOT be finished extremely soft with this consideration in order to last longer. And it is also recommended to order a little bigger size so that the body can have enough room to move easily without keeping on stretching the delicate silk fabric. · All Oscar Rossa silk has extra anti-split finishing procedure during fabric processing. This special procedure will make the delicate silk fabric more durable to use, although it may compromise a little bit on the softness. In the meantime, the silk fabric was processed as soft as possible. As time goes by, it will become softer and more comfortable after absorbing moisture during use. · Benefit of Silk: Silk is the most hypoallergenic of all fabrics because of its natural protein structure. It contains natural proteins and 18 essential amino acids including the protein albumen. Silk proves beneficial to those with sensitive skin conditions.
