Alessandro Dell'acqua

The Neapolitan who turned a lucky number into one of Milan's sharpest labels.

Alessandro Dell'acqua
Re-checked daily
Alessandro Dell'Acqua, born in Naples in 1962, is the Italian designer behind N°21 — the name drawn from his birthday and his lucky number.

Apprenticed to a Neapolitan dressmaker at thirteen, Dell'Acqua trained at the Accademia di Belle Arti in Naples before moving to Milan. He launched an eponymous line in 1996, showing his first prêt-à-porter at Milan Fashion Week, and shot campaigns with photographers including Juergen Teller and Steven Klein. Along the way he designed La Perla's first ready-to-wear line (2002–2008) and led Borbonese and, briefly, Brioni's womenswear.

Since 2010 he has run N°21, his own label, with Italian manufacturer Gilmar holding a stake since 2015 and a headquarters in Milan's Porta Venezia. He has also designed for Rochas, Les Copains and a capsule for Tod's — by 2022, a third of N°21's turnover came from Japan.

Alessandro Dell'acqua shopping FAQ

Is N°21 really Alessandro Dell'Acqua's own brand?+

Yes. Since 2010 Dell'Acqua has run N°21 (Numero Ventuno) as his own label, and it is the project he is best known for today. The name comes from his birthday and lucky number — he was born on 21 December 1962 in Naples. If you want the designer's current vision under his full control, N°21 is where to find it.

What is the difference between Alessandro Dell'Acqua's eponymous label and N°21?+

Dell'Acqua launched his eponymous line in 1996, but in 2009 he parted ways with it after losing the use of his own name and creative control following disputes with his production company. He responded by founding N°21 in 2010, a fresh label he owns and directs. So the signature "Alessandro Dell'Acqua" line and N°21 are two distinct chapters — N°21 is the one he steers now.

What is Alessandro Dell'Acqua's signature aesthetic?+

His work is unmistakably sensual, feminine Italian womenswear — think transparencies, lace, silk and a play between masculine tailoring and soft, romantic lines. He is often described as a master of quiet eroticism, drawing on the great divas of Italian neorealist cinema. If you love clothes that feel refined rather than overtly provocative, his hand is easy to spot.

Who is Alessandro Dell'Acqua and why is he notable?+

He is an Italian fashion designer born in Naples in 1962, celebrated for a sensual, feminine approach to womenswear. He founded his own eponymous line, later created N°21, and held high-profile creative roles across Italian and Parisian houses. Few designers have shaped contemporary Italian femininity as consistently across three decades.

Is N°21 by Alessandro Dell'Acqua worth buying?+

If you want designer-level Italian clothing without couture pricing, N°21 is a strong contender — quality has long mattered to Dell'Acqua, who notably left his earlier label in 2009 partly because he could no longer check the product. Expect fine fabrics like silk, cashmere, wool and leather and a feminine-meets-tailored sensibility. Start with a piece that carries his signature, such as a transparent blouse or a sharply cut skirt.

Where should I start if I'm new to Alessandro Dell'Acqua's N°21?+

Begin with the pieces that distil his point of view: a sheer or lace-trimmed top, a fluid silk dress, or modern knitwear — a nod to his roots in knit design. These show off the transparency and soft sensuality he is known for. From there it is easy to build toward his more tailored trousers and outerwear.

Was Alessandro Dell'Acqua really an apprentice at 13?+

Yes. At just 13 he became a part-time apprentice to a Neapolitan dressmaker, an early start that grounded his feel for craft and cut. He went on to study at the Accademia di Belle Arti in Naples before moving to Milan to build his career. That hands-on beginning shows in the precision of his clothes.

When and where did Alessandro Dell'Acqua launch his fashion career?+

He began in 1995 with a knitwear line called AA Milano, which evolved into his signature label, and presented his first ready-to-wear collection at Milan Fashion Week in 1996. His first menswear line followed at Pitti in Florence in January 1998. Milan has been the home base of his work ever since.

Which major fashion houses has Alessandro Dell'Acqua designed for?+

Beyond his own labels, he has held a string of notable roles: creative director of Borbonese from 2000, designer of the first La Perla ready-to-wear line from 2002 to 2008, creative director at the knitwear house Malo, head of women's wear at the Parisian house Rochas from 2014 to 2020, and a capsule for Tod's in 2018. That breadth across knit, lingerie-influenced and Parisian codes informs his own design language.

Why is Alessandro Dell'Acqua's brand so popular in Japan?+

Japan has become one of N°21's most important markets — by 2022 the label generated about a third of its total turnover there and opened its first freestanding store in Tokyo. The brand's refined, detail-rich femininity resonates strongly with Japanese shoppers. It is a good sign of the label's international standing.

Does Alessandro Dell'Acqua's N°21 make more than just womenswear?+

While he is best known for womenswear, his career has long spanned menswear, accessories, footwear, eyewear and fragrance, dating back to his eponymous line in the early 2000s. N°21 today offers a contemporary wardrobe across categories. Look to clothing first if you want the purest expression of his sensual signature.
