I am a long time customer, i have about 6 of your dresses and they are all a size 12 based on your size chart and they fit pretty well if not perfect. My latest purchase though i followed the size chart and the dress is swimming on me to the point i could have easily gone done a size (the top may still have been too big) but didnt cause the chart was obviously wrong for this dress. It isnt even available anymore so i cant get a better sized one. You should have style specific charts because this has seriously made me reconsider buying from you, and before this i would have called you my favourite dress shop. If i add a belt its do-able but still seems big.
