Frequently Asked Questions
Do these costume-onesies run true to size?
Many buyers report these onesies run a bit small. Measure your child's height and chest and consult the product size chart; if between sizes or if you want room for pajamas underneath, choose the larger size.
Can I machine wash these and still keep the costume details intact?
Most of these onesies recommend gentle machine wash or hand wash and laying flat to dry. Avoid high heat in dryers and aggressive washing to preserve decorative pieces and prevent small holes or loose eyes.
Are the hoods and tails safe for sleep?
Hoods and tails are generally fine for older kids, but for infants and very young toddlers remove any long strings or loose attachments at sleep time. For safe sleep for babies, follow standard SIDS guidelines and avoid loose bedding and costume elements in the crib.
