This "scrubs" outfit can fit a range of baby sizes since it has no feet...therefore if baby has long legs, the bottom hem just rides up a little higher on the legs.  It's probably too big for a typical newborn (i didn't try it on a newborn), but on a 6 month small baby it still fit just fine.  Baby didn't like the booties and cap, but the main outfit was comfy enough and made the point (of trying to dress up baby like a dr).
