Peplum

With Memorial Day behind us, stars like Emma Stone and Taylor Swift are celebrating summer's arrival in pretty white frocks.

From floral jeans to geometric-print trousers, patterned pants—spotted on the likes of Victoria Justice and Emma Roberts—add panache to any spring wardrobe.

The ladylike trend was spotted all over the runways this season, so it's no surprise that stars like Dakota Fanning and Scarlett Johansson are embracing the waist-cinching ruffles.
