Doen Celestine Dress in Black Velvet Size S Small

Doen Celestine Dress Size S (small) IMPORTANT: I had this dress tailored to fit smaller and then just bought the XS instead and had the tailor remove the darts she added. The lines where the darts used to be are on the back. I tried to photograph them but they're hard to see since the dress is black and the lines are faint.
