Here's a crown-worthy long prom ball gown that combines traditional style with modern details. The upscale long designer dress from La Femme is constructed of tulle fabric from the asymmetrical neckline to the floor. A ruched sheer bodice offers a peek of the trendy corset stays on this beautiful one-shoulder formal dress, while the fully-lined long skirt opens in a side slit before reaching the floor in a figure-flattering a-line shape. A rich design for prom, military balls, and other formal events, this long prom ball gown by La Femme is overflowing with eye-catching style.
