Vintage clothing sizes are different from modern sizes for three main reasons: historical measurement standards, vanity sizing inflation, and cultural differences between countries.

| 58 | XL/48 | 48 | 58 | 116 | 45.7" |
| 60 | XXL/50 | 50 | 60 | 120 | 47.2" |

1. Historical Measurement Standards
Before widespread standardisation, garment sizes were based on actual body measurements. A size 36 dress had a 36" bust. Modern sizes are abstract numbers that no longer correspond to measurements.
2. Vanity Sizing
Starting in the 1980s, US manufacturers gradually increased garment dimensions while keeping size numbers the same — or even reducing them — to flatter customers. This 'size inflation' means a modern 12 contains much more fabric than a 1960s 12.
3. Country Differences
US, EU, UK, and USSR each developed independent sizing standards. A Soviet size 52 jacket, a US size 42 jacket, and a UK size 42 jacket are the same garment cut differently.
