How It Works
International Clothing Size Conversion
Clothing sizes vary by country. This converter uses the standard offset for women's clothing.
Conversion Formulas
UK Size = US Size + 4
EU Size = US Size + 32
Italian Size = US Size + 34
These are approximate guidelines. Actual fit varies by brand, style, and body proportions. Always check the specific brand's size chart when possible.

Frequently Asked Questions
Are these conversions exact?
They are standard approximations. Brand-specific sizing can vary by 1-2 sizes. European brands especially vary, so always check the brand's own chart.
How do men's sizes convert?
Men's sizes are typically simpler: US and UK use the same chest/waist measurements. EU adds 10 to the US size (US 40 = EU 50).
What about Asian sizes?
Asian sizes (Japan, Korea, China) run 1-3 sizes smaller than Western equivalents. A US 8 might be an Asian L or XL depending on the brand.
