Recommended 3-piece set for graduation ceremonies, entrance ceremonies, and school events - Slimming effect

This is a jacket and dress set.
The thin cardigans in sizes 5, 6, and 7 were purchased separately from the set to be worn indoors when the jacket is removed. These are also included.
This is an elegant outfit featuring a chic black jacket and a monotone floral print dress.
It can be used for a wide range of occasions, from formal events to ceremonies.
For your reference, I had intended to use it for entrance and graduation ceremonies, but I only ended up using the inner dress once. The jacket and cardigans are unused.
At the time, I believe I was around 162 cm tall and weighed up to about 78 kg. Even then, I felt it had plenty of room.
It creates a slimming effect. Please use this as a reference.

Both the jacket and dress are made of machine-washable material. (Washing instructions included.)
