You can update anything from ‘My Events’ if you have not checked out. Select the event that you need to edit. Select your event date at the top right to open the side panel. From here you can update a look, add or remove participants, say you will pay for someone's entire look, update your event date, or the name of your event.
If you have already checked out, you can update your sizes up to 30 days before your event and if you have participants you can track the status of your participants. If you need to add or remove items, change your event date, or change anything else, you will need to reach out to Customer Care and one of our agents will be able to update the order for you.
