Surf’s up in the city, and it looks great. For her resort collection, Miuccia Prada infused high style with a beachy attitude. She opened her show with color-spliced looks in the shades of Miami Beach — sand, coral and aqua — albeit taken down in the interests of chic. These were typically draped in back over short skirts. Prada’s other big message: bold prints, worn in multiples or with shirts and varsity sweaters. And throughout, she tied one (or more) on, knotting skirts, tops and even Bermudas and bikinis, a note that referenced languid island life while adding a touch of sass.
