Fit is true to size. There is a section on the sides that offers some give, so unlike your typical linen top, this one has a bit of stretch to it. Stick with your usual size - size up if you are in between sizes. Model is wearing a medium. Fabric is sheer but not too sheer - model is wearing a black bralette underneath so that you can see the coverage. Longer in the back than in the front with a rounded hemline. Cap sleeves sewn in and an open v-neck at the top.
