I ordered the Black 2 in a size Large for a party. Sadly, it did not arrive in time, but arrived today. Fit wise, it is perfect. I was able to cinch the back ribbon lacing (which comes in the package, along with the neck piece) tight and it fits very well. I have broad shoulders, and am 5’2″ tall, with a medium, curvy build. It works well with a 4-layer tulle petticoat underneath. The length works for me with a very low heeled shoe and no length or other alterations are required. If you are in between sizes and wondering about buying a Medium, the one thing I can say is that the neck piece is a tad on the smaller side, so if you neck is larger, you might want to choose a larger sized dress.
The reason for my review is to say that, while I cannot attest to the quality of the fabric in some of the styles offered for this item, the fabric used for Black 2, which is a black/gold pattern, is excellent, with a good weight, and it looks and feels like a substantial poly satin jacquard, has a lovely lustre, and is not at all cheap. The dress is well-stitched and constructed (I am also a seamstress). I am really pleasantly surprised. Similarly, looking at the other styles offered, it appears that Black 1 and Red are using the same quality fabric, so if that is the case, then I would heartily recommend those styles, as well.
I am disappointed this dress did not arrive in time for the party I planned for it, but it is of such a nice quality, I may keep it to wear another time!
