I made the adult medium and they fit perfectly (I wear a ladies size 8). The rise is just right in my opinion :: not too low and not too high. I chose to make them out of a thrifted sheet, so I used the hemmed edge of the sheet on the bottom thus eliminating a step. When I make the next pair (and I definitely will be making more) I'll shorten the pattern a little bit to compensate for the pre-hemmed leg. The tie on the front is just a piece of twill tape sewn on for fun not function.
I'm thinking a couple of these made into cropped pajamas would be fun too! If you'd like to see what others are making from Weekend Sewing, take a peek here.
