This was a find, I also found a smidge in navy. It’s hard to identify certain fibers with exactitude so I will just tell you what I think. This is a very nice medium weight shirting with soft drape. It is opaque but a light color so how you wear is up to you, light colors always show a little. I burned no synthetic. This feels like a linen modal blend but it may just be linen extra laundered. In any case it is really nice esp for a big summer shirt. There are stripes woven within a twill weave. Color is ivory.
