Made by City Chic the dress size L would fit a size 20. The dress has a zip front which ends 13 cm above the hem from the neckline. The front and side of the dress has tucks both at the bottom of the front and at the sides of the dress. This creates both interest and shape. There are also smaller tucks just below the shoulders. The sleeves are a cap style. The fabric has a stretch for ease of wear and comfort.
