I ordered one size up as I usually do when I am unsure of the fit of a top but should have ordered the correct size. I wear a small but ordered a medium, and it is a bit looser than I would like, however, it still looks great and has the perfect amount of flow! Since I ordered this one size up, the sleeves run big, and I have to roll them to get the desired fit. What I love about wrap blouses is they can be dressed up or down. This blouse looks great with jeans or with a pencil skirt for a more professional look. This blouse looks as advertised and runs true to size. It is not sheer nor too thick. It is a deep V neckline so I usually wear something underneath for more coverage. I ordered mine in a size medium (should have ordered in my usual size, small, though) in the color blue.
