TRYING ON A COSTUME: When trying on a costume, we strongly recommend you do not try the accessories enclosed. This will limit the chances of accidental damage and will ultimately facilitate the exchange or return of the costume.

SHOE RETURNS: Shoes must be unworn, and unmarked (Without scuffs or marks). Trying them on in a carpeted area will ensure they remain eligible for return. Shoe boxes are an important part of the product presentation and must be returned undamaged, without postal labels.

INCOMPLETE / STAINED COSTUMES/ITEMS: Any item that has been worn, used, altered, is missing pieces, or is without the original packaging will Not be refunded.

WAREHOUSE PICKUP RETURNS/EXCHANGES: The 14-day period begins the day the order is ready for pick up. If a return is requested when a customer comes to pick up the order, we will issue it within 14 business days for the pickup day. For exchanges, please note that while we will exchange a costume’s size for you on site, we will not search the site for you to find a different style. If you wish to exchange the costume, you ordered for a different style you will have to have the Item number and size ready for us when you come to pick it up.

INELIGIBLE ITEMS: If an item arrive to the warehouse but is not eligible for return or exchange based on the above criteria, the item will only be returned to the customer if they authorize us to charge their credit card for the applicable return fees. If no authorization is given to send it back, the item will be held for 30 days until it is disposed of.

A NOTE ABOUT COSTUME STYLES: Costume styles [colors and fabrics] are subject to change without notice due to the manufacturer's production. These changes, no matter how slight, are sadly beyond our control. We do our best to catch these issues before they arise, however, the manufacturers do not always notify us of these variations. We take great care to reflect any changes in the website descriptions and images as soon as we become aware of them. If you notice any discrepancies before we do, please let us know so we can change our descriptions and photos to provide a better experience for all of our customers. We apologize for any inconvenience this may cause and we thank you for your understanding.
