UK to US dress: example starting from UK 12–14
In this site's general women's dress chart, UK 12–14 shares a row with US 8–10 and EU 38–40. Its example waist is 28–30.5 inches and hips 37.5–40.5 inches; the bust reference on that row is 34.5–38 inches.
Use this as an approximate starting comparison. If the dress is fitted at the waist but looser over the bust, the waist may be the limiting measurement and change which US size works.
Check the actual dress before accepting the US label
US sizes may be graded differently by each manufacturer, especially for formalwear and structured garments. The published product dimensions override the generic international comparison.
When your measurements straddle two rows, keep both candidate sizes until you check fabric stretch, lining, closure and alteration allowance.
How this guidance is checked
These sources support the measurement method and help check real-world variation. They are not presented as one universal brand-size table.
- ISO 8559-2:2025 — Size designation of clothes — Primary and secondary dimension indicators — International Organization for Standardization (ISO). Clothing methodology: size designation should be based on defined body measurements rather than assuming universal retail labels.
- ISO 8559-3:2018 — Methodology for body measurement tables and intervals — International Organization for Standardization (ISO). Clothing methodology: body measurement tables are population- and interval-based rather than one universal brand-independent chart.
- Ladies Size Guide — H&M. Cross-check for women’s US/UK/EU clothing labels and bust, waist, and hip body measurements.
- Women's Clothing and Underwear Size Charts — Calvin Klein. Second-brand cross-check for women’s pants, dresses, outerwear, and the variation in numeric sizes at similar body measurements.
