Onesies are pretty adjustable for your little one. The bottom panel folds up and each stitch can be used as a button hole so they can be made a little shorter or longer as needed. They are very easy to get your baby in and out of as they completely open up and allow the baby to be laid on them and basically wrapped into them. They can be made in any colors and can even have add-ons such as a removable bow tie or a bunny tail.
Plain onesie = $12
Onesie with a removable bunny tail = $15
Onesie with a button on tie = $15
Onesie with a ruffled bottom = $18
