Frequently Asked Questions
Italian vs US Sizing Explained
The sizing systems in Italy and the United States evolved independently, reflecting different approaches to garment manufacturing and fit preferences. Italian sizing prioritizes precision and body-conscious fits, while American sizing has historically offered more relaxed fits with additional ease built into garments.
Women’s Apparel
Italian women’s sizes start at 36 and progress in increments of 2, while US women’s sizes typically use even numbers starting from 0 or 2. An Italian size 40, which is considered a medium in Italy, corresponds to a US size 6. This 34-number difference remains fairly consistent across the size range. Italian designers create clothes with the expectation that they will fit closely to the body, following the natural silhouette without excess fabric.
Men’s Apparel
Men’s Italian suit jackets and shirts use a numerical system that differs from US sizing. For jackets, subtract 10 from the Italian size to get the US equivalent (Italian 50 equals US 40). For dress shirts, Italian sizes are measured by collar circumference in centimeters, while US shirts use inches. An Italian 40 shirt collar translates to a US 15.5 to 16 inch collar, depending on the brand’s fit.
Footwear Sizing
Both Italian and other European countries use the Mondopoint or Paris point system for shoes, where sizes increase by 2/3 of a centimeter per size. This creates a different scale than the US Brannock device system. The conversion between Italian and US shoe sizes is not perfectly linear, which is why half sizes sometimes appear in conversions. Italian shoes are also renowned for having a narrower last (the foot-shaped form shoes are built around), which means width can be as important as length when selecting the correct size.
Regional Variations
Within Italy, some regional variations exist, particularly with smaller boutique brands. Northern Italian brands might fit slightly differently than southern Italian brands, though these differences are minimal compared to the overall Italian-US sizing gap. High-fashion Italian brands from Milan often have the most fitted cuts, designed for runway-inspired silhouettes.
Tips for Shopping Italian Fashion
Before You Shop
- Measure yourself accurately using a soft tape measure, taking bust, waist, hip, and inseam measurements
- Keep a record of your measurements in both inches and centimeters for easy reference
- Research the specific brand’s reputation for sizing – some Italian brands fit larger or smaller than others
- Read customer reviews on retail sites to see if items run small, large, or true to size
- Consider your body shape and how Italian tailoring typically accommodates different proportions
When Shopping Online
- Look for detailed size charts on the retailer’s website that show measurements for each size
- Compare your body measurements to the garment measurements, not just size numbers
- Check the return policy before purchasing, especially for international orders
- Read the product description for fabric composition – stretch fabrics offer more flexibility in fit
- Look at how the item fits on models and check if the model’s measurements are provided
In Physical Stores
- Try on multiple sizes to find the best fit, as sizing can vary between different garment types
- Bring shoes similar to what you’ll wear with the outfit to check length and proportions
- Move around in the fitting room – sit, bend, and raise your arms to test comfort and fit
- Ask sales associates for advice on how the brand typically fits
- Consider how the garment will fit after washing, as some Italian fabrics may shrink slightly
For Shoe Shopping
- Try shoes on later in the day when your feet are slightly swollen for a more realistic fit
- Wear the type of socks or hosiery you plan to wear with the shoes
- Walk around in the shoes for several minutes to check for pressure points or discomfort
- Consider width as well as length – Italian shoes often run narrow
- Leave about a thumb’s width of space between your longest toe and the end of the shoe
