If you are petite, you need a dress that can make you look taller and your legs look longer. A short dress with a structured cut such as an asymmetrical one is the perfect choice. Moreover, high heels are essential with a short dress especially if you want to look taller.
Also, pick some accessories that could create the illusion of length, like a scarf or a long collar. Avoid large and ample cuts and long dresses, high-heeled platforms and too big accessories that will only make you look smaller.
