Start at the shoulders
Shoulder placement controls the rest of the silhouette. Structured jackets should sit close to the shoulder point; relaxed styles may intentionally fall beyond it.
Leave room for the base layer
Measure your reference jacket while wearing the kind of shirt or knit you expect underneath. Chest room that feels generous over a tee may feel tight over a sweatshirt.
Check sleeve and hem together
Raise and cross your arms to test mobility. Then note where the cuff and hem land, since sizing up can add length as well as width.
