Finished knitting the body and sleeves and it was WAY too big in the shoulders and the armpit did not fall in my armpit at all. Ugh.

Ripped it out and started over. Did some measuring and math and came up with this: Every increase row for a total of 76 rows, sneak in extra increases on wrong side row 16, 36, 56, 76. Somehow my stitch counts for body vs sleeves end up a little off, so I had to rip back a little and fangle things.
