Why Sizing Varies
Bra sizing is notoriously inconsistent. Factors like vanity sizing, the outdated "+4 method" vs. modern direct measurement, and regional standard conversions make finding the right fit a challenge.

Common Questions
Why is my size different across brands?
Brands use different grade rules and measurement standards. Some still use the legacy +4 method, while others design around modern, direct measurements. Fabric tension and wire width also play critical roles.
Does Victoria's Secret run small?
Their bands are often quite elastic, but their cups can run inconsistent across different lines. Many find they need to size up in the cup compared to more structured European brands like Panache or Empreinte.
