The photograph here doesn't do this beautiful cotton shirting justice. The blue stripe one almost looks like it has ribbon stitched into the fabric.
These are two separate pieces of silk.
Interestingly this fabric is typically use for the abaya that the ladies wear here in the Middle East. I purchased a slightly heavier weight one which I think I will use to make a nice soft pant suit - I have seen something similar with a long shirt for the jacket.
