What the number means
The flannel and knit-set listings declare a 31 inch inseam; the selected Regular M joggers declare 29.5 inches. These are published product specifications. We have not physically measured the selected garments before or after washing. The numbers do not become a tested shrinkage forecast simply because the products contain cotton.
Do not manufacture a percentage
No fixed shrinkage percentage is calculated from fiber composition. The public records do not supply a verified post-wash measurement protocol for these exact selections. A general fabric rule or customer anecdote would not establish the result for the current color, size and production version.
Keep size families apart
A staff answer mentions 31.5 inch inseams for certain Tall jogger options. That does not change the selected Regular M source value. The shared chart also has a conditional Tall-length note, not a universal instruction to add two inches to every posted dimension. Exact selected specifications take priority over a casual extrapolation.
Practical purchase sequence
Record the selected identifier, read the complete current care label and clarify any essential dimension before purchase. At receipt, compare the correct garment with its actual label and applicable return conditions. We provide neither a guaranteed fit nor a washing experiment, and the body chart is not a substitute for garment measurements.
