N°21 (Number Twenty-One) is Alessandro Dell'Acqua's creative rebirth project, launched in 2010. The brand represents a new chapter for the Neapolitan designer, who has infused it with a more personal, free and immediately recognizable vision, taking its name from his day of birth and lucky number.

The aesthetics of N°21 constantly play on contrast and overlap. It's an ongoing dialogue between men's and women's wardrobes: austere fabrics and tailored cuts blend with hyper-feminine details like lace, feathers, sequins, and transparencies. The result is a "bon-ton" but rebellious style, sensual but never vulgar, where a sports sweatshirt can be paired with a precious skirt with ease.

The brand has achieved global success thanks to its ability to make luxury portable in everyday life (sophisticated daywear). Her shoes, often embellished with knots or crystals, have become true objects of worship, a symbol of a modern, ironic and conscious femininity.
