Scroll through our collection and say hello to your newest OOTD.</p><h2>FAQs</h2><h3>What’s the difference between a formal dress and a cocktail dress?</h3><p>Cocktail dresses are your go-to for parties, date nights, and semi-formal events where you want to dress up but keep it fun. They’re usually shorter, like a <a href="https://www.hellomolly.comhttps://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. Choose a tulle, lace, or satin cocktail dress and dress it up with elegant accessories. If you’re part of the bridal party, a <a href="https://www.hellomolly.comhttps://www.hellomolly.com/collections/maxi-dress/occasion_bridesmaid-wedding-guest">maxi dress</a> is the classic choice, but a polished <a href="https://www.hellomolly.comhttps://www.hellomolly.com/collections/day-dresses/occasion_bridesmaid-wedding-guest">day dress</a> can still work for outdoor or destination weddings. Just be sure to follow the couple’s dress code and color palette.</p>
