How do parents see their costume details in my portal?

Once you have added costume details to your classes, you need to turn on the option to share those details on your portal. 

To enable that option, go to More > Settings > Portal Settings in the left menu.  Then click on the "Costumes" tab.

 

Once you check the "Share Costume Details" box, more options will display that you can select whether to share or not.

 

After you save those selections, parents can see costume details for the active classes their students are currently enrolled in.
