This is such a pretty top. i do not feel it runs big, as another review mentioned. to fit the sleeves comfortably (i do not have large arms at all) i did choose to take a small over my usual xs so the body is a bit llonger than shown on the model (a bit more of a tunic fit on me). it is really a pretty top either way, the xs fitting like it does in the picture on the model and the s fitting a bit longer. worried just a bit that it might develop holes as some tissue tees do.
