This is a very nice sheer cotton.  Sheer in the sense that you'll need a bra that is skin coloured as you can see through it a tad.  It has a nice low neckline without being racey and the sleeves are long.  I'd  recommend this for jeans, or for  work-layering.  It's a fantastic buy.  I'm going to wash it by hand because I know it'll shrink due to the high cotton content, but I prefer doing these type of tees by hand otherwise they have a tendency to lose shape after a while, why not treat it like a delicate- I also would use delicate on the machine and light tumble dry.
