Frequently Asked Questions
Everything you need to know about your Onesies Downunder order.
How do I find the right size for my onesie?
We recommend referring to our comprehensive size chart located on each product page. Our onesies are designed with a comfortable stretch, so if you are between sizes, we suggest sizing down for a snug fit or sizing up for a more relaxed feel.
Is your packaging discreet?
Yes, absolutely. All orders are shipped in plain, unmarked mailers or boxes with no mention of 'Onesies Downunder' or the contents on the exterior to ensure your privacy.
What is your return and exchange policy?
Due to the hygienic nature of our products, we can only accept returns or exchanges on items that are unworn, unwashed, and still in their original packaging with tags attached. Please contact our support team within 14 days of delivery to initiate a return.
How long will it take for my order to arrive?
Domestic orders typically arrive within 3-7 business days. International shipping times vary by destination but generally take between 10-21 business days. Tracking information will be emailed to you as soon as your package departs our warehouse.
What materials are your products made from?
Quality is our priority. Most of our onesies are crafted from a high-quality blend of 95% cotton and 5% spandex, providing a soft, breathable, and durable experience that holds its shape after multiple washes.
Do you offer international shipping?
Yes, we ship to most countries worldwide. Shipping costs and delivery estimates are calculated at checkout based on your specific location and the weight of your order.
