The long-sleeve romper carries a festive holiday letter print, the pants add warmth for winter gatherings, and the bow headband tops off the look for the tree-side picture. Made from soft cotton and polyester, it stays comfortable through a long day of relatives passing the baby around. Sized 3-18 months — also a sweet gift for new parents.
