Some events are worth marking on your calendar, and Reformation’s Summer Sale, starting today, is one of them. It’s a rare opportunity to grab items found in the closets of the rich and famous at a fraction of the price. Take, for instance, this knit dress (available in multiple colors) worn by A Quiet Place actress Lupita Nyong’o—now just $69. Or these chic sandals spotted on Gabrielle Union during the Olympic Games, now available for $104. These items are still in stock, but they won’t last long. If they’re your style, may I suggest adding them to your cart, ASAP? Prefer something different? Reformation’s Summer Sale features hundreds of markdowns. But don’t worry—below I’ve rounded up the good ones to help you find the best deals quickly.
