Giorgio Armani re-defined tailoring in the '80s with his softly fitted suits - and ever since Jodie Foster wore a custom white two-piece to collect her Oscar in 1992, they've been an eveningwear favorite. These cropped straight-leg pants are cut from shimmering silk and cotton-blend that holds its shape and doesn't crease. Style them with pointed brogues, as seen at the Spring '18 show in Milan.
