For a wedding calling for cocktail attire, one can never go wrong with a little black dress. We love this super feminine style by Halston Heritage - the structured full skirt and notched neckline add just enough flair to a classic LBD. Another option for a fun, modern twist on cocktail attire this summer is the crop top and full midi skirt combination (I absolutely adore this look - if only I weren't pregnant!). We love Alice + Olivia's simple nude crop top with the ethereal silver lamé skirt. Both looks can be accessorized with sparkly earrings, embroidered clutches and single-sole strappy sandals.
