Here's a muslin of the tunic that I sewed up on Sunday. Most of the Machiko Kayaki patterns that I've sewn up have been small in the armholes, so I wanted to see if this pattern had the same problem. It did. So, I ended up altering the pattern a bit and added some depth to the armholes. Hopefully, that will create a better fit!
(I'm curious because I'm a seamstress who is mystified by people who make muslins - maybe I just like shortcuts, but I never bother! If the pattern needs fudging/altering, I just do it out of the final fabric.)
