I have the Chalk and it's just another name for a creamy white. It's somehow see-through, and your bra color and shape will be easily visible through the material. Got it on sale, but not sure I would have kept it if I had paid full price due to the near-transparency. However, the material is comfortable and light on the skin, which is all I really need for the shirt. The L sizing was appropriate to what I expected.
Point is lost for the color, not the quality.
