If you ask Mary-Kate and Ashley Olsen [1], the chicest Summer evening look might just be one of your bedtime essentials [2]: a long black robe. The designer duo behind The Row and Elizabeth and James attended a launch party in matching looks. Mary-Kate wore an Elizabeth and James Resort '18 maxi while Ashley's silhouette comes from the Fall '17 collection complete with bishop sleeves. Both ladies slipped into the functional, flat sandals they designed [3], which seemed to be the only style note to confirm the season.
You see, Mary-Kate and Ashley stick to floor-sweeping numbers for parties [4] year-round, which is easy enough if you ask us — especially when the dress is comfortable. The Olsens design similar roomy pieces for both of their labels, which you can shop ahead (along with similar options). We're not sure what would stop you from re-creating such a simple ensemble — one that you could literally sleep in if you so desire.
