This calculator is based on historical data from the Wikipedia article on vanity sizing and may not be accurate for all brands.
How does this calculator work?

This calculator uses historical bust measurements from the US misses standard sizing tables from 1958 to 2025 to determine equivalent dress sizes across different eras.

For example, a size 8 dress in 2025 has a bust measurement of approximately 35 inches, which would have been closer to a size 12 in 1958.

The calculator works by:

  1. Converting your current dress size to its corresponding bust measurement
  2. Finding what dress size in your selected year would have the same bust measurement
  3. Interpolating between known measurement years (1958, 1970, 1995, 2011, and 2025) for years in between

This approach provides a more accurate representation of how dress sizes have changed due to "vanity sizing" over the decades.
