I made these as part of a swap on another board.
This is quite a wide pattern, even considering the leggings are meant to be on the looser side. The rise is also strangely long and I actually chopped a bit off the top after trying it on my 4yo. I'd probably leave off the seam allowances for an average sized child and reduce the rise a few cm. The pleats are a little bit fiddly to get even, but give a really nice look when finished, so it's worth the effort.
