Worked the S size with larger needles to get M size.

Modds:

• added 4 more rows in the back yoke to achieve wider body at the back
• Longer body finished with 3 rows of reversed stockinette and I-cord bind off
• No increases in the collar (fronts worked straight)
• Longer collar (I followed the instruction for the largest size) finished with 3 rows reversed stockinette and I-cord BO
• Sleeves finished like the rest of the sweater (3 rows of reversed stockinette and I-cord BO)

I may add some pockets….
