Once your order is complete, you will receive a tracking number from the U.S. Postal Service. Orders are processed Monday through Friday from 10 a.m. to 5 p.m. Processing time is between two and five business days depending on volume.
The merchant uses USPS Ground Advantage for a transit time of four to seven days. Items on preorder status are sold out and ship as soon as inventory is available.
Making sure you receive items that fit is a priority for the merchant, and for this reason, they offer a 30-day exchange policy that will cover sizing issues that you may experience for most items excluding underwear. The merchant does not offer refunds for sizing issues, but they can issue store credit or an exchange for eligible items. Underwear, supplements, and items sold during special events are not eligible for return or exchange.
To help ensure that you get the best fit, What Waist accepts returns within the United States for eligible items returned in new condition with original packaging and tags. The customer is responsible for all shipping fees to and from the warehouse. If you need to return more than one item it is suggested that all items are processed in the same request and sent back in one package with the return label.
