M&S's new collaboration with Ghost has arrived There are 15 limited-edition dresses to choose from Courtesy Marks and Spencer’s latest collection with Ghost has arrived and it’s full of pretty dresses perfect for wearing all summer long. This is the second collaboration between the brands following their successful first launch back in November. The edit features 15 limited-edition dresses that capture the classic British aesthetic of Ghost gorgeously. Think tea dress-style shapes, elegant floral prints, feminine detailing like ruffling and billowing sleeves. Courtesy Super versatile, each dress would work as well for a formal event as it would a weekend around town. Simply add a pair of strappy heels for a beautiful wedding guest outfit or throw on a pair of sandals and a straw tote for a more casual summer look.
