Three measurements in, one numeric dress size out — matched across US 0–18, UK, EU and Italian sizing with the closest-fit row highlighted.
How to use

- Read across the highlighted row for UK/EU/IT equivalents.
Frequently asked questions
Which measurements matter most for dress size?
Bust, waist and hips — in that order for fitted styles. The calculator matches all three independently against each numeric size band; if they point to different rows, the general rule is to buy for the largest measurement and have the rest tailored in.
Why do US, UK, EU and IT numbers differ so much?
They are different numbering systems, not different body sizes. Most brands keep stable offsets: US 8 ≈ UK 12 ≈ EU 38 ≈ IT 42 — in other words UK = US + 4 and EU = US + 30. European sizing follows the same idea as the EN 13402 designation standard (derived from body dimensions), while US/UK use their own numeric ladders. The chart shows all four so you can shop across regions.
What does “US 0–18” cover here?
The standard misses range: US 0 through 18, which corresponds to EU 30–48 and UK 4–22 under the +4/+30 offsets. Each step is one numeric size (US 0, 2, 4…) with its own bust/waist/hip band in centimeters.
Is my dress size the same as my shirt size?
Usually close but not identical — dresses are graded through the hip, while tops are graded through the bust and shoulder. If your hips are wider than the chart’s dress row suggests, dresses are where you feel it first.
Should I trust the size on the tag?
Use it as a starting point only. Vanity sizing means the same tagged size can differ by several centimeters between brands and decades — your measurements plus each brand’s chart beat the tag.
What about stretch knits or wrap styles?
Stretch knits and wraps tolerate one size down; structured woven dresses do not. The chart describes standard woven-fit sizing — treat elastic styles as forgiving exceptions.
