Miss Minuet strapless party dress size S NWT

NWT adorable white party dress with black accents (lined). It has three tiers of a crinoline-like fabric, molded cups, and ties in the back. I was inspecting it and noticed a small spot on the back, down the center (pic 9). It’s hidden by the black bow (pic 10). Spot is only on outer most layer (pic 11). Not sure where it came from - this has been sitting in my closet. Taking $5 off the price. Please contact me with any questions prior to purchasing. Comes from a smoke-free, pet-loving home!
