Our Return Policies

First Pair Risk-Free Policy


Because they’re, well, underwear, we can’t accept exchanges or returns on used items. BUT you can try your first pair on your first order risk-free for 30 days! 

If you ordered the wrong size of period underwear, we’ll send you a different pair at no cost or offer you a standard refund within 30 days of delivery (excluding original shipping fees).

If your order included multiple period underwear, open, wash, and wear one pair only. That way if you don’t love them, any unopened packages from the same purchase will be eligible for an exchange or standard refund (excluding original shipping fees).

All unopened packages will be donated to local organizations to support people in need.

Click here to initiate an exchange or refund:

  1. Use your order number and zip code to enter the returns and exchanges portal.

  3. When you have initiated an exchange or refund for all desired items, click “Continue with Return” at the bottom of the page.

  5. Hit “Submit” to submit your request or “Go Back” to change your selection.
    5a. If your exchange or refund generated a shipping label, use it to send back any items in brand new, unopened condition. Please do not send back the used pair of Period Underwear. As part of our First Pair Risk-Free Return Policy, we'll still provide an exchange or refund for that pair, in addition to any brand new items returned to us.
