I tried on this mock neck today for fun, in a size up, and was suprised that it was so form fitting in my size up. I expected it to be short but not so snug in the waist area. If you have a long torso like me this will hit you in a really odd spot, even if you plan to layer it. The positive on this is that the material is incredibly soft. It's a really nice double lined rulu with smooth rulu on this inside (vs. heathered or textured).
