Kynan has the outfit in a size 0. I had the same problem with the waist of pants being too big in one size but the legs too short in the smaller size when Kynan started off in size 0s. Someone in this thread suggested putting a little stitch in the waistband at the back of the pants. I couldn't be bothered LOL so just had to put up with a few weeks of constantly pulling up Kynan's pants until his tummy filled out a little more.
