"Gregorio" Fit Profile – Isaia Napoli

The Gregorio model represents a classic, structured sartorial silhouette from Isaia, offering a refined balance between traditional Neapolitan tailored elegance and executive structure:

  • Fit: Classic Modern Fit. Features a comfortable, natural cut with balanced chest dimensions and a lightly sculpted waistline for an elegant, masculine silhouette.
  • Shoulder: Soft Neapolitan Shoulder (Spalla Camicia). Designed with light padding and natural sleeve-head construction to ensure a crisp shoulder line with optimal freedom of movement.
  • Construction: Full Canvas (Fully Lined). Crafted with a traditional floating full horsehair canvas interlining paired with a smooth 100% light yellow cupro lining to maximize structure, drape, thermal insulation, and long-lasting shape retention.
  • Pockets: Formal Flap Pockets (Tasche con Patta). Adds a polished, sophisticated finish suitable for executive business and autumn/winter formal occasions.

Description:

Crafted in Italy by Isaia Napoli, this 2-button suit is tailored from soft, high-grade 100% Wool Flannel in a rich Grey shade highlighted by a bold mustard yellow and brown plaid check pattern. Built on the Base Gregorio model, it presents soft shoulders (spalla camicia), classic notch lapels, and formal flap pockets.

Constructed with a traditional floating full canvas interlining and fully lined in a bright light yellow 100% cupro lining, it delivers outstanding body-molding structure, cozy warmth, and supreme crease resistance for cold-weather tailoring. Signature handcrafted details include hand-stitched buttonholes (asole fatte a mano), hand-sewn genuine dark corozo buttons, a tan felt undercollar accent with red logo embroidery, and the iconic red coral lapel pin. Includes original spare corozo buttons and matching thread set for custom sleeve finishing.

The matching trousers feature a clean flat-front cut complete with classic belt loops.
