What is a mermaid wedding dress?

A mermaid wedding dress is a gown fitted through the bodice, waist, and hips, before flaring out into a full skirt at or below the knee. There is some nuance between the mermaid and the trumpet style of gown, which flares around the thigh. But they both fall into the category of “fit-and-flare” dresses, where the key is creating form-flattering silhouettes in the bodice and the hips.

For the purposes of this roundup, we’re including any dress that we find stunning that follows the general mermaid-like silhouette of fitted up top and flared somewhere below the waist, as the aesthetic appeal of trumpet and mermaid wedding dresses is quite similar.

Are mermaid wedding dresses uncomfortable?

It’s no secret that mermaid wedding dresses have a more restricted and form-fitting silhouette, but that doesn’t have to mean they’re uncomfortable! It’s simply a matter of perspective. When choosing a silhouette, whether mermaid or anything else, you’ll want to think about how much you’ll be moving around on the wedding day.

It’s true, mermaid wedding dresses will result in less mobility than you’d have with a flowy skirt, but that’s part of how it achieves that lovely aesthetic. Fret not if you’re concerned about comfort. If you want something that you can wear for hours on end, look for a mermaid gown that’s lighter in weight, which’ll make moving around your wedding venue that much easier. You’ll also want to think about your fabric choices, too. Some fabrics are more inherently comfy than others.

All of that said, the silhouette of the mermaid wedding dress is only one of many factors that impacts whether or not a dress is comfortable.

Lace Mermaid Wedding Dresses

Lace mermaid wedding dresses combine the whimsy of lace with the form-flattering figure of the mermaid silhouette. It’s the perfect type of gown to create either a boho or an elevated, elegant aesthetic. Opt for bold lace patterns on your mermaid wedding dress for a more modern look, or go floral for something more classic.
