I purchased this item new. I only wore it for a few hours in the morning for a piano recital. There are no noticeable stains, but please understand that this is a used item as it has been worn once. The front length is about knee-length, and the back length covers the feet. It's a simple white dress with scattered stars, making it both glamorous and cute. The length from the shoulder strap to the back hem is approximately 121.5 cm (photo 7). The length from the shoulder strap to the front hem is approximately 83 cm (photo 8). It has five layers, giving it a moderate volume (photo 5). Since the front length is around the knee, it won't get in the way when using the pedals, making it recommended for piano recitals!
