Navy jacket and skirt set, formal design, perfect for business. Also ideal for graduation and entrance ceremonies. The collar is double-layered, and the black velvet collar can be removed. You can wear it according to the occasion. The buttons are wrapped in black velvet and navy fabric, making them very stylish. Size is 9. The skirt is knee-length. I wore it about 1 or 2 times after purchasing. It has been stored at home, so please understand.
