No. 21 – Alessandro Dell’Acqua finds the perfect balance between considered tailoring and refined femininity for No. 21’s Pre-AW18 collection. of which this black crepe shift dress is a leading piece. It’s tailored in Italy for a relaxed fit with a crystal-embellished grosgrain panel, then falls into a straight skirt that is shaped with an inverted pleat across the back. Style it with lipstick-red pumps for a dramatic after-hours contrast.
