Bridal Inner Corset Tap Pants Size: D70 The back neckline drop is about 28cm. I wore it from the ceremony to the first half of the reception, and I didn't experience any itching or irritation at all! The tap pants are made of a smooth material, and the waist is elastic. If you have any questions about how it looks when worn, such as the back view, feel free to comment. I will add photos.
