Frequently Asked Questions
Are these costume-onesies warm enough for outdoor trick-or-treating?
Yes — the flannel/plush fabric used in these rompers provides good insulation for fall evenings. For very cold weather, layer a lightweight long-sleeve onesie and a coat over the romper for added warmth.
How should I choose the right size?
Always consult the seller's measurement chart and compare chest, length and leg measurements to your child’s current clothing. Customers often report these rompers run slightly big, so if between sizes you can size down for fit or up to allow layering.
Can I machine wash these without shrinking or pilling?
These items are designed to be machine washable, and many buyers note they retain softness and shape. Use a gentle cycle, cold water, and tumble dry low or air dry to minimize pilling and extend garment life.
