They’re usually shorter, like a <a href="https://www.hellomolly.com/collections/mini-dresses/occasion_formal-cocktail">mini or midi</a>. Formal dresses are typically longer and made for black-tie events, weddings, school formals, and extra-fancy occasions. Both styles are stunning — it just depends on the vibe.</p><h3>What kind of shoes go best with cocktail and long formal dresses?</h3><p>For cocktail dresses, strappy heels, block heels, or sleek heeled sandals are always a win. For long formal dresses, elevate the look with classic stilettos or pointed-toe heels, especially styles with a little sparkle.</p><h3>Can I wear a cocktail party dress to a formal wedding?</h3><p>Totally.
