Frequently Asked Questions
What distinguishes an evening gown from a formal dress? ▾
An evening gown is a floor-length silhouette specifically designed for white-tie and black-tie galas, charity balls, and red carpet events, crafted from opulent textiles like satin mikado, velvet, or hand-beaded tulle. Formal dresses encompass both floor-length gowns and upscale midi silhouettes appropriate for formal weddings, dinners, and cocktail receptions.
What undergarments are recommended for open-back evening gowns? ▾
Most of our designer gowns feature integrated bra cups and structured bodice boning for natural support. For plunging backlines or off-the-shoulder styles, we suggest seamless adhesive silicone lift cups or low-back contour shapewear.
What are the domestic US and international shipping options? ▾
Standard domestic US shipping is complimentary on all orders of $200 or more (flat rate $15 for orders under $200). Worldwide international shipping is complimentary on orders of $500 or more. Priority expedited delivery is available at checkout for imminent event dates.
