We completely get it, we change our minds too! While we wish could, once an order is placed, we are unable to alter or cancel it at this time. We hope to have a cancellation window one day in the future.

Should the item(s) not work out, make sure to exchange for a preferred style or return for a refund. As a reminder, domestic return shipping is free.

We want to speak to you too! Contact us with any questions, concerns, or feedback. We will be sure to get back to you within 48 hours. However, please note that inquiries sent on Fridays will receive a reply the following Monday, but possibly sooner.
