I think the model is wearing a larger size, per the first review. i am 5'2" and 105 lbs and the xs fits about the same in length but not nearly voluminous. so you should order up if that is what you want. this will be perfect for some long summer flights instead of a wrap, since the sleeves will be more convenient and i always look schlumpy rather than elegant in a shawl! if it had some cashmere or another softer fiber i would be totally in love with it.
