Piazza Sempione specializes in heavy-rotation basics. The Italian brand has perfected the slim-fitting, ankle-cropped trouser; for Resort, its best-selling Audrey pant comes in classic wool gabardine, colored lace, geometric-print jacquard, and what seems like a legion of other fabrications. How about a go-to dress that will take you from coffee date to conference meeting to cocktails and beyond? With its simple bust and flattering A-line skirt cut from a brushstroke-pattern fille-coupe, look 12 from the new lineup fits the bill. But some of the best looks here tweaked the label's classic formula. A rippling maxi skirt with mid-thigh slits was cut from a techno silk the color of a swimming pool, and button-up shirts in a seventies-inspired wallpaper print (which channeled Prada's "ugly" prints from Fall '12) had collars embellished with fun plastic paillettes.
