I ordered a size 4 and it fit perfectly! It is slightly long, but with heels might be close to what I am looking for. The size was what I thought it would be and fit very nicely. It arrived in the time they specified and I had no problems at all with ordering this dress.
I would definitely order again!
The dresses were beautiful on a number of different physiques. For the purpose of the day, the dresses were just right. My hem on the dress was slightly uneven, but not terribly noticeable when on. My only issue with the dress is that I overestimated my size and missed the exchange deadline.
