NOTE: Double your underarm increases!!! The arms were way too tight with only the recommended three, i’ve gone up to seven on each side to be able to wear this with a sleeved shirt underneath in the size Medium.
I also adjusted the sleeve positions as the pattern places them with the back of the garment being larger than the front. I am all front and no back, so i through it on the form and placed them where my human body actually is. If you don’t have a form, try them on and mark with clip on stitch markers for the appropriate sleeve positions.
