I believe the combination of a white cardigan and a navy sleeveless dress can be worn for formal occasions. This was prepared for my child's elementary school entrance ceremony. The items were purchased separately, not as a set. The dress features a ribbon and logo embroidery. - Color: White and Navy - Design: Sleeveless dress - Embellishment: With ribbon - Embroidery: With logo embroidery The cardigan has some pilling. It will be shipped folded. Thank you for looking.
