Grown-up elegance is the Giorgio Armani signature—but he took his Emporio Armani collection in a decidedly more youthful direction. What with all the baby blues and Bazooka pinks and minidresses parading two and three at a time down the runway, it felt almost like prom night. The comparatively young models, sporting trompe l'oeil stockings that looked like knee socks, contributed to the overall effect.

Working in black, white, and gray mixed with pastels—and an airy silhouette strikingly similar to that of his main line, down to the pointy flats—Armani opened with a bubble skirt and jacket, a checkerboard fur shrug tossed over one shoulder. After that, he worked his way through a teenage army of tiny frocks: abbreviated A-lines, innocent baby dolls, and swingy trapezes accented with bows or crystals, some as bright as hard candy. Here, as in his signature line, he kept pants to the sidelines: The few pairs he did show were cropped and worn with abbreviated jackets left unbuttoned to expose the somewhat ill-advised bra tops, one sour note amid the show's nonstop sugar high.
