Numbersea Women's Open Back Formal Evening Party Prom Gowns, a V-Neck long chiffon creation, embody a timeless standard of quiet luxury. Meticulously cut from premium chiffon and fully lined in polyester, the fabric offers a soft, weightless drape that remains opaque and skin-friendly. The built-in bra ensures a secure, smooth silhouette, while the waist belt defines the line without interrupting the gown’s fluid movement. The floor-length, flowing skirt creates a romantic, accessible elegance perfect for weddings, galas, or formal ceremonies. Limited in production to preserve its refined exclusivity, this gown invites wearers to invest in a piece with lasting value.
Provenance and value: Numbersea’s approach to this gown centers on longevity and care for the wearer’s experience. It’s offered in a generous 16-size range, ensuring a flattering fit across silhouettes, with a bespoke option available upon request. This is more than a dress; it’s a timeless investment for formal milestones—weddings, proms, or milestone celebrations—designed to endure as a favorite in years to come. With meticulous attention to detail and a restrained palette, the gown remains elegantly relevant beyond fleeting trends.

Return Policy
Please keep in mind that all dresses are uniquely made to order to keep costs low for our customers. We also understand that colors on your computer screen can be a little different to how they appear in person. For these reasons, we encourage you to order a Swatch (free shipping) to help you decide.
ZAPDRESS will issue a full refund including shipping for any damaged, defective, or mis-shipped items. If your item arrives damaged or defective, please reach out to Contact Us directly for assistance with processing your return.
FOR ALL STANDARD SIZE DRESSES, SHOES, AND ACCESSORIES:
ZAPDRESS will issue a full refund of the cost of the returned product if you are not satisfied with your item(s). Contact our Customer Service to initiate the return process within 7 days upon receiving your item(s). The item must be returned in its original condition (if eligible per the return policy).
Please note:
* The item must be unworn, unwashed, unaltered, undamaged and with the original tags attached. We cannot process the return of any faulty item.
* Original shipping fee & return shipping fee will not be refunded.
* As all items (including standard size) are made-to-order, we cannot afford to accept the ‘buy-many-keep-one’ purchase. Our customer service team may cancel an order believed to have been made with that intention.
FOR ALL CUSTOM SIZE DRESSES:
At ZAPDRESS, we understand that you may want the dress to ideal fit! To help you out, we offer custom sizing on most of our dresses. Custom sizing takes the same amount of time to make and ship to you!
A few things to remember about custom dresses:
Custom dresses are made specifically to the measurements you provide (bust, waist, hips, height, and hollow-to-floor). That means no one else will be able to wear that dress once it's made. Because of this, we are unable to accept any returns on custom dresses. Please double check your measurements and color choice before ordering.
We understand that sometimes small alterations are needed, we offer limited alterations reimbursement for only our custom sizes. Simply send us a picture of your receipt from the tailor and your order number and we'll do the rest! Yes, it really is that easy!
EXCHANGE POLICY
We do not offer an exchange service for any products at this time. Because all items are made-to-order, we do not have ready-made dresses or products that can be shipped in exchange for your returned items. You will need to return unwanted items (if eligible per the return policy), and then place a new order for the replacement items. All new orders are subject to the current production period.

* We reserve the right to refuse the return if received in an unacceptable condition.
