This is an extremely useful mesh knit called "lycra corset" (I don't know if that's the official name or just the name my supplier gave it). It is much firmer and has much more springback than the power mesh linings, but is still lightweight, so it's great for corsets and bras, swimwear, dancewear, etc. The color of this one is black, and it stretches only if you want it to, in both directions, springing right back into shape. It has equal, moderate stretch lengthwise and widthwise. BLACK
