Size conversion FAQs
How do US sizes convert to UK and EU sizes?+
Add 4 to a US size for the UK equivalent (US 8 = UK 12) and add 32 for the EU size (US 8 = EU 40). Australian sizes match UK numbers. The converter and chart above handle every system side by side.
Are letter sizes (S, M, L) the same everywhere?+
Roughly. S usually spans US 4 to 6, M spans US 8 to 10 and L spans US 12 to 14, but brands cut letters differently. When a product page lists garment measurements, trust those over the letter.
What size should I order at Fashorio?+
Fashorio lists US sizing. Convert your local size with this tool, then check the size guide on the specific product page. Measurements vary by style and fabric, and the product chart always wins.
What if I am between sizes?+
For structured pieces (denim, corsets) take the larger size; for stretchy or flowy pieces (knits, wrap styles) the smaller usually works. Product pages note when a style runs big or small.
Do these conversions work for jeans waist sizes?+
No. Jeans measured in inches (26, 27, 28…) are waist measurements, not dress sizes. As a rule of thumb, US dress size 4 ≈ 26 to 27" waist, size 8 ≈ 29 to 30". Check the product size chart for exact numbers.
