I recently purchased a Bonobos suit, and I want to get the sleeves on the jacket shortened. However, the buttons at the cuff are working, which means I would need to get the sleeves shortened at the shoulder. Does anyone have experience having work like this done? It just seems that this could throw off the proportions, since the sleeves appear to be tapered from the shoulder toward the cuff.

Also, if anyone has recommendations for a tailor in San Francisco, I would appreciate it.
