it is not absolutely transparent and it is made up of several layers that make it a good dress and not a stand dress. The mystery of the size is soon unveiled, on the back it is tied with a ribbon like a corset so as to be able to easily adapt to different sizes. The bodice is already reinforced so that it can also be worn without a bra. We come to the length .. in front comes flush to the ground and will allow you to wear a medium-high heel and on the back is just longer (does not create endless train, but a nice elegant line). I think it can be worn up to size 46 comfortably … a 48 maybe … Just to give you an idea I’m 1.70 tall, weight 60 kg, I wear a 44 / M and I have a second bra, and the dress is really ok for me.
