Plus-Size A-Line Formal Gowns and Party Dresses

Plus-sized a-line dresses are figure-flattering and fit nearly all body types. Forgiving by design, the a-line dress is fitted and narrow at the top and tapers out from the waist in strong straight lines, visually creating the silhouette of the letter for which it is named. Explore this assortment of plus-size a-line dresses offered by Simply Dresses that includes formal evening gowns, a-line plus party dresses, and short a-line cocktail dresses in plus sizes. Whether you’re attending an ultra-formal special event or looking for a chic and sexy a-line party dress, you’ll find an impressive variety of styles at Simply Dresses.
