I cut the shirt pieces from the bottom of the shirts, so I didn't have to do any hemming. I also re-used the collars and sleeves. I won't point out the mistakes I made.
I then took an old pair of dress pants that Mr. Curly no longer wears and created two little pairs of pants using a pattern I found at Dana-Made-It. Curly Boy's have a smaller waist, but longer legs than Curly Baby's.
And yes, in the first picture, the pants on the left do seem to have legs of two different lengths. And they are - just not as much as the picture makes it look like. Honestly, once they're on, you can't even tell.
