Size 7 SOCIAL Mourning 3-piece set

This is a mourning dress from S O C I A L.
The black color is a subdued shade, and it comes with a lace blouse and a tie made of the same lace, creating an elegant mourning dress.
I am selling it because the size no longer fits.
Jacket measurements: shoulder width 42 cm, sleeve length 53 cm, length 48 cm.
Skirt measurements: elastic waistband, length 67 cm, pencil skirt style.

For reference, I am 151 cm tall, and the length falls slightly below my knees.
As I am an amateur, my description may be insufficient. I hope someone who understands that this is a used item will purchase it. Please feel free to ask any questions in the comments.
It's a good quality item and will be very useful if the size fits you.
