How the three systems line up
In the numeric rows of the chart, the UK size is the US size plus 4 and the EU size is the US size plus 32. US 8 is UK 12 and EU 40. US 2 is UK 6 and EU 34.
The letter rows use the same UK and EU numbers: S is UK 8 and EU 36, M is UK 10 and EU 38, L is UK 12 and EU 40, XL is UK 14 and EU 42.
Worked examples
UK 12: US L in the letter chart, US 8 in the numeric chart, EU 40. EU 38: US M or US 6, UK 10. US 4: UK 8, EU 36.
The bust, waist and hip columns are the numbers to trust when a label and a chart disagree.
Why the same size fits differently
PeachSunday's size guide says sizing varies slightly by style and fabric. The chart is a starting point, not a guarantee, since a stretch knit and a woven cotton fit differently at the same labeled size. A style marked oversized or relaxed fit is cut larger than the chart on purpose.
Other stores publish their own charts, and they can differ from this one. Use each store's own chart for its own clothes.
Measure first
Take your bust, waist and hip with a soft tape over the undergarments you would normally wear, then match them to the columns above. The size guide shows how to measure each one, and how to pick your size online walks through the method.
If you are between sizes
The size guide says to size up for a relaxed fit and size down for something more fitted, especially for stretch fabrics like ponte, rib knit and satin blends. Read the fit notes on the product page, and send a message through the contact page with your measurements if you are still unsure.
