Every child is proportioned differently, and each shirt fits differently, too, so this idea just may work for you, like it did for me. Landon had a few onesie shirts, which fit him around his torso, but they were becoming too short for snapping closed. So, I got out my fabric scissors and cut off the onesie bottom part of the shirt. Because the shirts were make out of knit/jersey material, no hemming was necessary! They can be worn and washed without any sewing, and Landon is getting quite a bit more wear out of his clothes!
