By Kids Only Airplane Shirt

My son loves his "huggy shirt" (as he calls it). He honestly has one on 24 hours a day (he requests to sleep in one, too). I have one that is a size too small and others that are the "correct size." Here's what would make the shirt perfect...I love the "tightness" of the smaller shirt, but the arms and torso are way too short. If the shirt that "fit" him could be tighter it would be a real hit and I would buy more. He needs it to be tighter to really give that consistent proprioceptive input that his little body craves. Don't get me wrong, he loves his shirt...I just know that he could get more out of it with a tighter fit.
