I’m absolutely in love with my hoco dress! The quality is amazing, the fabric is soft and comfortable, and the fit is perfect. It’s stylish, flattering, and looked stunning at the dance. I got so many compliments all night long. Shipping was fast, and it’s totally worth the price. Highly recommend!

Frequently asked questions

What is a mermaid mother of the bride dress?
A mermaid gown is fitted through the bust, waist, hips and thighs, then flares at or below the knee. The fitted line creates a dramatic, formal shape for evening weddings.
Is a mermaid dress comfortable for a long wedding day?
Choose a style with some stretch, a slit, or a flare that starts below the knee. Try sitting, walking and climbing stairs in the dress before the wedding.
When should the mother of the bride wear a mermaid gown?
Mermaid silhouettes suit evening, black-tie and formal ballroom weddings. For daytime or garden ceremonies, a softer A-line or tea-length style is usually more comfortable.
