We highly recommend double-checking all details before placing your order.
However, if you need to make changes, please reach out to us as soon as possible!

We want your clothing to look great and last as long as possible, so we recommend following these care instructions:

Machine wash with cold water
Avoid using bleach, as it can damage the fabric
Do not tumble dry, as this can cause shrinking and fading
Avoid dry cleaning, as it can be harsh on the material

By following these simple care instructions, you can help ensure that your clothing stays looking and feeling its best for years to come.

All orders are shipped from Ohio in the United States.

We aim to ship all U.S. domestic orders within one business day.
Orders placed before 12PM (EST) are typically shipped the same day.

Please note that slight delays may occur after weekends, public holidays, or during peak holiday periods.

You can expect to receive a shipping confirmation once your order has been packed and shipped.
Be sure to check your junk or spam folders just in case our email has ended up there.

We understand that waiting for your order can be frustrating, and we apologize for any inconvenience caused by the delay.
There could be several reasons for the delay, such as unforeseen logistical issues or customs clearance procedures.
We suggest keeping an eye on your order's tracking information for the latest updates on delivery estimates.
If you require further assistance, please don't hesitate to reach out to our customer support team.

Sadly, we can’t modify your shipping details once your order has been shipped.

We recommend reaching out to the shipping carrier directly to update or change your shipping details.
If your shipment is unable to be delivered due to an incorrect address, the shipping carrier should typically return this back to our warehouse.

If the shipping carrier does return the original shipment, we will reship this to the correct address.
However, if the shipping carrier does not return the original shipment, unfortunately, we are unable to accept any responsibility for the package.

We understand that privacy and discretion is crucial. All shipments are shipped in plain boxes, bubble mailers or polybags.

International orders are dispatched twice a week—on Wednesdays and Fridays.

Shipping costs will vary depending on a variety of factors such as location, size and value of your order.
Shipping via DDP (Delivery Duties Paid) will ensure there will be no additional fees to pay upon delivery.

We offer Standard and Express shipping on most international routes.
With our international shipping partner, we’ll find the lowest possible shipping rate for your order—ensuring you pay as little as possible in fees, while still receiving reliable delivery from a trusted carrier.

Duties and taxes are calculated at checkout, so you'll see the full cost upfront with no surprise fees upon delivery.
With DDP (Delivery Duties Paid), your parcel clears customs faster and landed costs are more predictable—handled entirely through our service provider’s trusted network.

We accept the following payment options:

On your billing statement, the card charge will be displayed as "SP*ODUAU."

Should your card face consistent rejection, it's possible that your bank is preventing the transaction.
We recommend contacting your bank to ensure they allow the transaction to proceed.

Kindly verify that the card you're using is authorized for purchases beyond the United States.

We get it, sometimes you and your new purchase just don't click or you accidentally chose the wrong size. Don't worry, we're not the jealous type. You can return any eligible item to us within 14 days of delivery, as long as it's still in tip-top shape with all the tags and labels attached.

When trying on your new threads, please be gentle with them. If you decide to return something, make sure it's clean, unwashed, and free from any yucky stains, marks, or odors.

Unfortunately, if we receive a returned item that doesn't meet our returns policy, it won't be eligible for a store credit and will be shown the door.

We know shipping costs can be a bummer, but you'll be responsible for covering any costs to return your product(s). Once we receive your return, our cool warehouse team will give it a once-over before processing your store credit.

We don't offer exchanges, sorry! However, you're welcome to return any eligible items for a store credit.

Sale and retired items are final sale and cannot be returned.

If your order arrives damaged or defective, please email us at support@onesiesdownunder.com with your order number and clear photos of the issue.
