Understanding Dress Sizes
Dress sizes vary significantly between countries and brands. While the US uses numerical sizes (2, 4, 6, etc.), Europe uses different numerical systems, and the UK has its own unique sizing. This calculator considers bust, waist, and hip measurements to provide the most accurate size conversion across major international sizing systems.

Body Type Considerations
Hourglass Shape
Bust and hips are similar with a defined waist. Typically fits standard sizing well. Look for fitted styles that accentuate the waist.
Pear Shape
Hips wider than bust. May need to size up for hips and tailor waist. A-line and fit-and-flare styles work best.
Apple Shape
Carries weight in midsection with slimmer legs. Empire waist and wrap dresses provide the best fit.
Rectangle Shape
Bust, waist, and hips similar measurements. Creates curves with belts, ruffles, and peplum styles.
Brand Size Variations
Designer Brands
Often run smaller than standard sizing. May need to size up 1-2 sizes. Focus on precise measurements rather than size numbers.
Fast Fashion
Tend to run larger or vary significantly. Check customer reviews for specific brand sizing advice.
Asian Brands
Typically run 1-2 sizes smaller than US/European sizing. Always check Asian-specific size charts.
Important Considerations
- Always measure yourself while wearing appropriate undergarments
- Measure at the fullest part of bust, smallest part of waist, and fullest part of hips
- Keep the measuring tape parallel to the floor and snug but not tight
- Brand sizes vary - always check individual size charts when available
- Consider fabric stretch when selecting sizes (knits vs wovens)
- Different dress styles fit differently (sheath vs A-line vs wrap)
Frequently Asked Questions
How often should I remeasure myself?
It's recommended to remeasure every 6-12 months or after significant weight changes (5+ lbs). Body measurements can change due to exercise, age, or lifestyle changes.
What if my measurements fall between sizes?
Always size up if between sizes. It's easier to take in a garment than to let it out. Consider your largest measurement (usually bust or hips) when deciding.
How do I account for different dress styles?
Sheath dresses require precise measurements. A-line dresses are more forgiving at hips. Wrap dresses adjust to your measurements. Empire waist dresses focus on bust measurement.
Why do sizes vary so much between brands?
This is called "vanity sizing" - brands use larger size labels to make customers feel better. Also, target markets differ (junior vs misses vs women's). Always rely on measurements over size labels.
