The first layer sets the base; a sweater changes the silhouette. Sandro's men's Fall Layering edit is a place to think about that relationship before adding more to an outfit. Layering is easier to judge in the full outfit than one piece at a time. Look at the silhouette from the collar through to the hem, making sure the points where layers meet feel intentional rather than simply accumulated.
A sweater can sit beneath a jacket without disappearing into the look when the lengths differ. Keep trousers in view as you adjust the upper proportions, then remove a layer to see whether the remaining combination still feels complete.
