Great dress
This dress is gorgeous in person. it is so much softer than it appears the photo and the fabric moves well. what you can't see from the picture is that the bodice sort of overhangs the skirt by an inch or so which is really nice for accentuating a small waist and separates the top from the bottom in a cool way. 

i am 5'6" 135 lbs and curvy. 36-26-39 for reference. i ordered the 4 and it is loose although still flattering thanks to the forgiving cut. wish i had gotten a 2 but now they are sold
