Numero 21, unveiled in 2010 in Milan under the creative direction of Alessandro Dell'Acqua, carries a significant fashion legacy. Trained at the local Academy of Fine Arts in Naples and mentored by Gianni Versace, Dell'Acqua received acclaim in 2002 as the "Best Designer Women's Fashion." With a diverse career, including roles at La Perla, Malo, Brioni, and Rochas, he collaborated with artists like Vanessa Beecroft and Helmut Newton.

Existing for over a decade, Numero 21 melds modernity with femininity, incorporating elements from the male wardrobe into a contemporary and stylish collection. The brand's distinctive stylistic code lies in the seamless fusion of feminine and masculine shapes and fabrics. Dell'Acqua's focus on a genuine and meaningful approach results in a fresh pret-a-porter proposition that leverages his profound product knowledge.
