I usually wear size 6 or 8. In the description for the dress, it says "Dress runs small. We suggest ordering one size larger than usual". In addition, when I checked the size chart, for my measurements, a size 10 was applicable so I ordered a size 10. However, when I got the dress it was too loose especially up top. The top half sagged at the back. The bottom half fit ok but was not as tight as it should have been. The dress is beautiful though. I got it 1 week before the event that I purchased it for wearing to. Since I am in Canada, I wouldn't have had enough time to return it and get a smaller size. So I had to keep the size 10 and wear it this way, with the top back sagging. From the front, I looked great. From the back, not so much. Sometimes I would pull the front down to create the illusion of a scoop neck so that the back wouldn't pucker out. Bad experience. Next time I wont follow the warnings in the description nor the size chart. I will just buy the size that I always wear. Before I wear the dress again, I will have to get it adjusted.
