MEASURE, DO NOT GUESS
Manufacturer measurement diagrams for every cut the house produces, plus how to read them on a phone in a garage.
How to measure
Lay a garment you already wear flat. Measure a — chest, edge to edge under the arms — and b — length, from the highest point of the shoulder to the hem. Compare those two numbers to the diagram for your cut below.
Fit notes
Standard fit pieces sit close to the body. Heavy oversized pieces are cut deliberately wide through the chest and shoulder. Size up for hoodies worn over riding layers; size down for a closer T-shirt fit.

These are the manufacturer’s own diagrams. Screen-reader-readable measurement tables are being transcribed from them so the same numbers are available without needing to see the image.
