Under the Try-On Guarantee, you can get a refund or exchange for a different size on one pair of underwear that has been tried on, and you won't need to send them back. The Try On Guarantee only applies to one pair of underwear within 30 days of receipt.
If you bought more than one pair of underwear on your first order we recommend wearing and washing just one pair to make sure they are right for you. That way if you don't love that pair, the rest of your order will still be eligible for a standard return or exchange.
Please feel free to reach out to our Customer Service team either at hello@mackweldon.com, through our Contact Us form here, or via chat which is available Monday-Friday from 10am-5pm if you have any additional questions.
