What to Look for in Cocktail Attire

Cocktail attire is all about party-ready silhouettes, fun details, and shorter hemlines. To help you nail down the perfect cocktail attire for any upcoming wedding, it's always helpful to take the season and wedding venue into consideration. For summer weddings, we love breezy lace dresses in soft pastels and bright hues, while jewel tones and sequined fabrics feel especially appropriate for fall and winter nuptials. Finally, while cocktail dresses are generally a midi length or higher, you can still wear a maxi, but in this case, it’s best to opt for a more casual fabric.
