Overview of the COS Return Policy
If you are in a rush, here is the essential blueprint of how COS handles returns and refunds. While the rules are straightforward, missing a small detail-like removing a tag or using the wrong box-can cause your return to be rejected.

Return Window & Eligibility Requirements
To qualify for a seamless refund, your items must be returned within a strict timeframe and meet specific condition requirements.
Standard Return Window
COS enforces a strict 30-day return window. If you miss this deadline, your return will be denied, and the items will be sent back to you at your expense.
- In-Store Purchases: The 30-day countdown begins on the exact date printed on your physical register receipt.
- Online Purchases: The 30 days begin on the day the package was officially marked as "delivered" by the shipping carrier. This ensures you do not lose time while your package is in transit.
What Items Qualify for Returns?
COS expects returned items to be in perfectly resellable condition. To have your return accepted, ensure your items meet these rules:
- Condition: Clothing must be unworn, unwashed, and undamaged. Any items smelling of perfume, smoke, or showing makeup stains will be rejected.
- Original Tags: All original COS paper hangtags and fabric labels must remain firmly attached.
- Hygiene Liners: Swimwear and underwear must have their original adhesive hygiene seals fully intact and undisturbed.
- Footwear: Shoes must be returned in their original, pristine shoebox. Important: Do not use the shoebox as your outer shipping box. You must place the shoebox inside a separate, sturdy cardboard box before mailing it.
How to Return Items to COS
COS gives you a couple of different ways to return your purchases, but choosing the right method can save you money.
In-Store Returns (100% Free)
The easiest way to bypass any shipping fees is to return your items directly to a physical store.
- Locate any standalone COS retail store in the United States.
- Bring the unworn item with its tags attached.
- Provide your proof of purchase. For in-store buys, bring your paper receipt. For online orders, show the digital order confirmation email featuring the barcode on your smartphone.
- The staff will process your refund immediately.
Warning: While COS is proudly owned by the H&M Group, they operate as entirely separate stores. You cannot return COS items to H&M locations. For rules on returning H&M merchandise, check out our H&M return policy guide. Similarly, COS items cannot be returned to sister brands; see the & Other Stories return policy guide for their specific rules.
Mail-In Return Process (Online Orders)
If you cannot make it to a physical store, you can mail your online order back via UPS. Keep in mind that doing so will incur a $7.50 fee.
Step-by-Step Mail Return Checklist:
- Pack Your Items: Place the eligible, unworn items back into the original shipping bag or box.
- Insert the Return Form: Find the paper return slip included in your original shipment. Write down the correct return reason code next to each item and place this slip inside your package.
- Apply the Pre-Paid Label: Peel off the pre-printed UPS return label (included in your box) and stick it directly over the old shipping label.
- Drop Off at UPS: Take your sealed package to any authorized UPS Store, UPS Customer Center, or official UPS Drop-off location.
- Get Your Receipt: Always ask the UPS clerk for a physical drop-off receipt. This tracking number is your proof of return if the package gets lost in transit.
What if I lost my return shipping label?
Do not panic if you accidentally threw away your prepaid UPS label. If you have a registered COS account, log in, navigate to your order history, and you can generate and print a new label. If you checked out as a guest, simply call COS customer service to have a replacement PDF label emailed to you.
Refunds & Processing Time
Once you hand over your items, you likely want to know how quickly you will get your money back.
- Refund Method: Your funds will always go back to the refund method you originally used to pay (such as Visa, Mastercard, PayPal, Klarna, or a COS Gift Card). Store credit is generally only issued if you are returning an in-store purchase with a gift receipt.
- Processing Time: Mail-in returns can take up to 14 business days to process once they arrive at the COS warehouse. After the warehouse team inspects and approves your return, your bank or credit card company may take an additional 3 to 5 business days to post the funds to your account.
If you are looking for brands with faster mail-in processing, you might want to compare this with the Everlane return policy.
Exchange Policy
The COS exchange policy varies heavily depending on how you choose to return your items.
- In-Store Exchanges: If you bought an item (either online or in-store) and need a different size or color, you can easily exchange it for free at any physical COS store, assuming the store has the item in stock.
- Online Exchanges: COS does not currently process exchanges through the mail. If you bought a shirt online and need a medium instead of a large, you must mail the large back for a refund and place a brand-new, separate order for the medium on the COS website.
Items That Cannot Be Returned
To prevent any frustrating surprises, it is important to know which non-returnable items are strictly excluded from the COS refund policy:
- Final Sale Items: Any merchandise clearly marked as "Final Sale" at the time of purchase is yours to keep. These cannot be returned or exchanged under any circumstances.
- Opened Hygiene Items: Underwear, bodysuits, or swimwear where the clear protective hygiene seal has been removed, torn, or repositioned will be rejected.
- Pierced Jewelry: For strict public health and safety reasons, earrings and other pierced jewelry are completely non-returnable unless they arrive physically defective.
- Gift Cards: Physical plastic gift cards and e-gift cards cannot be returned or redeemed for cash, except in states where local laws require it.
Fees, Deductions & Exceptions
The biggest frustration shoppers face is the cost of sending items back. Here is a clear breakdown of the costs involved:
- Mail-In Return Shipping Fee: For 2026, COS automatically deducts a flat $7.50 return shipping fee from your final refund total when you use their prepaid UPS label.
- Restocking Fees: Fortunately, COS does not charge any hidden restocking fee on top of the shipping deduction.
- How to Bypass the Fee: The only way to avoid the $7.50 shipping charge is to return your online order in person at a standalone COS store, which is completely free.
- Defective Item Exceptions: The $7.50 mail fee is fully waived if your return is the result of a COS error-such as receiving the wrong item, a damaged garment, or a defective product. However, you must contact customer service before mailing the item back to ensure the fee is officially waived on your account.
Holiday & Extended Return Policies
During the busy winter gifting season, COS offers a generous holiday return policy extension.
Typically, for purchases made between mid-November and late December, the standard 30-day window is paused. Any items purchased during this peak promotional window can be returned or exchanged all the way through January 31st of the following year.
All standard eligibility rules (like keeping tags on and hygiene seals intact) still apply to holiday returns.
Customer Support Information
If a package is lost in transit, a refund is delayed, or you received a damaged item, the COS customer support team is available to help resolve the issue.
- Phone Support: Call 1-855-842-1822 (Toll-Free in the US).
- Hours of Operation: Representatives are available Monday through Sunday, from 9:00 AM to 10:00 PM Eastern Standard Time (EST).
- Live Chat: You can access the live chat feature on the official COS US website during regular business hours.
- Pro-Tip: Before you call or start a chat, have your 11-digit order number and your UPS drop-off tracking receipt ready. This will drastically speed up your support experience.
Frequently Asked Questions
Can I return COS items without a receipt?

How much is the COS return fee?

Can I return my online order to an H&M store?

How long do COS refunds take to process?

What should I do if my COS item arrived damaged?

What happens if I lost my prepaid UPS return label?
If you misplaced your label, simply log into your COS account and navigate to your order history to print a replacement. If you checked out as a guest, call COS Customer Service to request a new PDF label via email.
Does COS offer price adjustments?
No. COS does not offer price matching or price adjustments if an item you purchased goes on sale at a lower price after your original purchase date.
Conclusion
Returning items to COS does not have to be a stressful or confusing experience. To ensure you keep 100% of your refund, always opt to return your online purchases to a local COS storefront to easily bypass the $7.50 mail-in shipping fee. Remember to respect the strict 30-day window, keep all original tags securely attached, and never remove hygiene liners from swimwear or underwear until you are absolutely sure you are keeping them.
