We recently purchased 5 different pair of these pajama sets as gifts, but oddly all 5 sets had faulty Labeling inside the pj tops.
 Specifically they were not size extra small, but instead they were all actually very Large pairs with short sleeve & a matching bottom shorts size too.  oddly all 5 pajama sets -arrived with FAULTY labels; all read extra small, but the size that we received ere enormous size large.
