Trumpet Dress vs Mermaid Dress

If you’re looking for mermaid wedding dresses, you may be come across some that are called trumpet dresses, and vice versa. Technically, the difference between a mermaid dress and a trumpet dress is that while a mermaid dress has a more exaggerated “flare” tale, a trumpet dress flares more subtly. Some also say that while a mermaid dress flares below the knee, while a trumpet dress begins to flare at mid-thigh.

However, both have that fit-and-flare shape, and sometimes brands and companies use these descriptions interchangeably. So if you’re looking for flared wedding dresses, you may want to check out both mermaid and trumpet wedding gowns.
