Self-made dress S/M

The dress is the first dress I made myself, and the first time I sewed with satin fabric. I made this in a hurry for a party which shows in the workmanship; this is mainly visible when admiring the inside of the dress. From the outside quite neat and works well for other parties too. Double-layered fabric, not see-through. I am size S in the top, bottom M/L and the dress is made to my measurements. The fabric is some kind of synthetic fiber. On the side of the dress, under the armpit, there is a black invisible zipper because I couldn't find a white one at home in a hurry (last picture). Length: on someone 163 cm tall about to the knees / slightly above the knees.
