Check our size guide before ordering. Because this is intimate apparel, we can't accept returns once it's been worn for hygiene reasons — but we do offer a free exchange for a different size within 30 days, as long as the hygiene liner and tags are still attached and it hasn't been worn.
Yes. All orders ship in plain, unbranded packaging with no indication of the contents on the outside.
