This dress is so soft, flowy and comfortable! the material is very smooth and silky. i'm hoping it holds up well over time with washing. i am 5"5, 120lbs and i ordered a xs. the elastic waist is a tad tight but otherwise it fits perfectly - just as shown on the model in terms of length and how the top fits. i said it runs a large because normally i would order a s but i think if i did, it would be too long and the arm holes might be too big.
