No. 21 - This light-pink dress was unveiled as the debut look on No. 21's SS18 runway, paying tribute to creative director Alessandro Dell'Acqua's own design's from 1997. It's tailored for a slim fit with a flattering sweetheart neckline that's shaped with black shoulder straps. The front and back is ruched through the centre for a subtle note of texture. Showcase the low back by sweeping your hair up into a messy bun, before adding metallic stiletto heels.
