Strapless, black dress with split up the back to the upper thigh 39 inches long

This black dress is very sleek. Strapless. Good spandex material at the top to hold it in place as shown in the pictures material is thin, but not see-through when it stretches out in the picture with my hand. The split in the back goes to the mid to lower thigh, depending on body type. If you have more curves, it’s going to have a higher split to make sure while bending over it does not write up if that is a worry. My daughter wore black spandex shorts underneath And when she did bend over, I still could not see the shorts
