I wear a size 2 but occasionally a dress runs small and a size 4 fits. That happened in another dress I bought from Chadwicks. In this case, the size was accurate and the 4 was too big for me, so I had to return. It did not come in a size 2. I would highly recommend this dress, it is all cotton and just what you need in hot summer weather. It would probably need regular ironing, which is the downside because it is cotton, but it is a cute style.
