Size Guide

Find your perfect fit across Italian (IT) and EU sizing for women and men. Use the toggles to switch gender and system.

Elasticated waists & drawcords provide adjustability; closer fits favor the lower end of the range.

Use your Tops table above—outerwear typically follows the same block; consider layering room.

Measure your dominant hand around the widest part (excluding thumb).

Quick rule of thumb: For women’s apparel, IT ≈ EU + 4 (e.g., IT 40 ≈ EU 36). For men’s tailoring, IT ≈ EU. When in doubt, check each product’s brand-specific notes.
