I bought the white one a few years ago, and am now purchasing in a few different colors.  It's very lightweight, so perfect for spring/summer/fall to throw on in the morning to run errands, or just wear around the house with a tank top underneath it.  It's stretchy, and long, which is what I like, since I have a long torso.  I usually wear a small, so I ordered a medium and that was perfect.  Order one size up if you purchase.  Nothing fancy, but a nice staple item for casual wear.
