FAQs
Why does inch sizing differ from numeric?
US inch sizing (W26, W28) tracks actual waist measurement. US numeric (0, 2, 4) tracks dress size. They line up roughly but vanity sizing means a US 4 dress wearer might wear W27, not W26.
What's W30 in EU jeans?
W30 = EU 44 = UK 16 = JP 19. Actual waist measurement is the most reliable signal across all regions. When in doubt, measure your existing favorite jeans.
