I just finished this in size 98 with length added for my 105cm four-year old:

The front... It's hard to see, but I did do the two piece/mock wrap front, complete with little button loops and buttons. And yeah, I did cut the right and left pieces opposite to what's advised. Oops.


Back:


I added pockets in the side seams:


The only other small modification I made was to use a button at the neck closure rather than the recommended Velcro.

An inside-out photo... The bodice is lined, stitched in place by hand. A bit sloppily, I am afraid, but I think it will hold.


As I was sewing the bodice lining in place by hand, I realized I could have done it with the machine if I had skipped top stitching the seam that attaches the skirt to the outer bodice when the instructions said to do so. If you skip that top stitching, get the lining seam allowances carefully pressed and pinned (or wondertaped!) in place after the zipper is installed, you could top stitch that waist seam and secure the bodice lining all at once.
