The pattern sizing is 104-128. This was a bit big my almost 2 years old son but he's growing so fast and I wanted to still fit him in the fall or next spring. I cut size 104. I moved to pockets a little higher so it will look more like his size and I skipped the lower part with the rope. I was long enough like this. I could have made it even smaller and shorter but I liked the idea of him having more room in it.
I had some trouble with the pockets and to do a few tries with the scraps. Good thing that I did that because they didn't turn out right the 1st try but I was really pleased with them in the end. They look almost professional to me.
One other thing I like to point out is this really nice trick to make sure the zipper don't hurt the kid. I seen it done in a RTW jacket and it seems brilliant :
Here are some pictures from the park late in the evening when the wind started and we could enjoy our capes:
