Zegna Suits: Buyer's FAQ

How can I tell a Zegna suit is authentic? We authenticate every suit in-house, and the tells are in the details counterfeiters get wrong. We check the labels: genuine Zegna tailoring carries clean woven main and composition labels (matching inside the jacket's left inner pocket and, on suits, the trouser waistband) and, notably, no Zegna logo printed across the lining. We look for horn buttons rather than cheap plastic, a canvassed chest and neat, dense stitching, and we confirm the piece is Zegna-made, not merely cut from Zegna cloth by another maker. Most is made in Italy, Switzerland or Spain. Because details vary by era, we never rely on a single marker; if a suit doesn't pass every checkpoint, we don't list it.

What are Zegna suits made of? Zegna suits are wool, wool-mohair, silk and linen blends with canvassed, Italian-made tailoring — often in the house's own high-performance cloth. Every listing states the exact composition and our condition grade.

How should a Zegna suit fit? Zegna follows Italian sizing with a refined cut. Check the chest, shoulder and trouser measurements we publish per piece — a jacket can be tailored, but the shoulders should fit from the start.

Is a pre-owned suit worth it? Yes. The build lasts for years, so a pre-owned suit at a fraction of retail is sound value, and every pre-owned piece is graded transparently (Unworn with tags, Unworn, Excellent, Very Good). And every piece is authenticated — if one is ever proven inauthentic, we refund it in full — with a 14-day return policy, so you can buy with confidence.

How to Buy Zegna Suits

From the suits we inspect, check the shoulders and lapels, the horn buttons, any shine at the seat and elbows, and that jacket and trousers match as a set. We grade each of these before a suit is listed, new or pre-owned.

Wear a Zegna suit for formal occasions, or break the jacket and trousers into separates.

Rest it between wears, steam rather than iron, and have it professionally cleaned sparingly. Every suit at Sanpetuna — new and pre-owned — is authenticated by hand and backed by a 14-day return policy; if a piece is ever proven inauthentic, we refund it in full.
