Sweet Mommy maternity dress. I think it can also be used for formal occasions. It has chiffon sleeves, and can be worn as a sleeveless dress or as a half-sleeved dress by putting your arms through the chiffon part. I especially found the shoulder area helpful for covering my figure. It has a nursing opening. I used it only once at a friend's wedding and stored it after cleaning, but please consider this item as used. I am selling it because I no longer have the opportunity to wear it.
