## How it works

US/UK/EU dress sizes step by bust circumference: US 8 = UK 12 = EU 38 ≈ 91.5 cm bust. Letters (XS-XL) compress two numeric sizes each and vary most between brands.

## Assumptions

- Manufacturer charts vary; conversion outputs are the standard-mapping midpoint.
- Measurements are body measurements unless the tool labels them as garment measurements.
- Between-size results round per the rule stated in the FAQ.

## Common questions

### Why is my size different at every store?

Letter and number labels are brand conventions mapped onto real body measurements. Charts that print actual cm ranges are the only comparable layer, which is what this converter uses.

### What if I fall between sizes?

Round the direction that matches use: clothing and shoes generally round up.
