424 generally runs true to its labeled size, with denim and pants cut in straight or relaxed profiles rather than skinny. Bomber jackets tend to have a regular body with room for light layering. Check each product page for specific fit notes if a piece runs longer, shorter, or more oversized than standard. If you sit between sizes, consider the intended silhouette — a cleaner line may call for your usual size, while a slouchier look can handle sizing up.
