Personally, I think they're cute if the bow is not super huge. I think they are cuter on bald babies though. My first had some hair, not a ton, but enough and they just looked weird on her. My youngest was totally bald when she was born (she's 11 months now and still only has some peach fuzz) and I thought the bows looked adorable on her.
My sister however, thinks they look dumb on bald babies and better if the baby has hair.
So, if you like them, order them!
Oh and some are too tight if your child has a large head. Youngest DD has a bigger head (80th percentile) and some of the bows we had would leave elastic marks on her head they were so tight. Obviously we didn't have her wear those!
