The fabric is silky to the touch. Double layer. Normally, I would order a size 3 but it was sold out so I ordered a size 4. The size is off on this and the Silky Non-Wire! I wish they stated to go up a size in their "Details + Sizing" for these two. I have the Non-Wire bra in sieve and eyelet in different colors in a size 3 and I love them. For the Glace and Silky Non-Wire, you would need to go up a size. I only wear NU for bras and sport bras (Sieve Bra Top).
