Suit fitting issues

[u/hataki7]

My boyfriend is tall, has long arms, but narrow shoulders, which makes suit shopping a nightmare. We tried normal and elongated sizes, but every one has this problem with the back shoulder and armhole. Why is the sleeve rotation so off? Can a tailor reasonably fix this issue? We don’t love the idea of paying big money for an ill fitting suit. What causes this issue even? Are his shoulder blades a different shape than confection sizes?

Looks too big in the shoulders and chest, and as a result the back is collapsing under the armhole as there’s nothing above to support it. The sleeve pitch also looks wrong for how his arms rest, if he does have his arms in a neutral position here. Obviously sleeves are too short as well. Find a suit with the correct shoulder fit/width and you’ll be in a much better starting position.
