Why US Sizes Run Larger Than EU Sizes
A US size 8 fits the same body as a EU size 38. Why? Vanity sizing. US apparel makers gradually shrunk size labels over decades to flatter consumers, while EU sizing stayed closer to original measurements.

Notes
Vanity sizing is a marketing technique: shrink the size label so customers feel slimmer, increase emotional satisfaction, drive purchases. It started in US in the 1980s and accelerated. EU sizing has stayed more measurement-honest. Result: same physical body wears US 8 and EU 38, even though both labels imply size 8 vs size 38 differently.
FAQs
Are US sizes still drifting?
Yes, slowly. The same body labeled US 8 in 1990s often gets labeled US 6 today. 'Vanity sizing creep' continues. EU sizing has remained stable to the original ISO standards.
Which is more accurate?
EU. EU sizing maps to actual body measurements (bust, waist, hip in cm). US labels have drifted from any consistent measurement baseline. When ordering online, always check the brand-specific cm/inch chart, not just the size label.
