Mermaid wedding dresses are a popular choice among brides because they are designed to hug the body and showcase the bride's figure. This style of dress is fitted through the bodice and hips, and then flares out at the knee to create a mermaid-like silhouette. This style is particularly flattering on brides with hourglass figures, as it helps to highlight their curves. Additionally, mermaid wedding dresses often feature intricate details and designs, making them a beautiful and elegant choice for the big day.
