Shopping Tips
Gucci sizes are in Italian (IT) sizing. For men, subtract 10 from IT to get US size for pants (IT 48 = US 38 chest). For women, subtract 36 from IT and multiply by 2 to approximate US size. When in doubt, size up — Gucci tends to run slim, especially in tailored pieces.
Size Comparison
Gucci runs slightly smaller than Prada and similar to Versace. Compared to American brands like Ralph Lauren, Gucci fits noticeably slimmer. Their IT sizing aligns with other Italian luxury houses like Valentino and Dolce & Gabbana.
