Nope Satsuki uniform is a dress uniform. To get is form fitting you will need to sew in and invisible zipper into a side of along the back seem. This way you can get into unziped dress first then zip it close after for fit. This zipper will only start 2" to 3" below the collar of arm hole and 1" above the Skirt seam.
The skit part will need to be a seperate piece sew to the body just because you can's really do the type of pleading with 1/5 the body fabric offers you. It the game with ever gather shirt/dress.
But you will notice the pleat are much more prominent then the seam.
You can tell this one doesn't have the zipper in it as it's not form fitted. Makeing the two section much more apparent.
You can also notice the pleat start higher on the hips instead of a striagt line to help the pleats huge the body more.
