Frequently Asked Questions
Do these onesies run true to size?
Sizing varies by style and many parents report a roomier fit. Always check the seller’s measurement chart and consider sizing down if you want a snug nighttime fit; size up if you prefer layering or growth room.
Are these safe for overnight sleep with a hood?
Hooded onesies are generally fine for supervised sleep and lounging, but for unsupervised sleep it's best to ensure the hood is lightweight and does not cover the face. Remove bulky hoods if your child overheats or if a caregiver recommends it for safety.
How should I wash costume-onesies to preserve softness?
Follow care instructions: most of these are machine washable on a gentle cycle with cold water and tumble-dry low or air-dry. Turning the garment inside out and avoiding high heat reduces pilling and helps retain shape and color.
