Remember that
Clasica hooded coat from the 2009 Interweave Knits?
I knit two of them, one for me, one for DD. Anyway, my Clasica is way too big now...and I'm not inclined to frog it and re-knit it. I use it for a camp coat...who cares how sloppy it is, right?
Anyway, here is another Clasica, but shorter this time, no hood, and sleeves are narrower (on purpose, I cast on fewer stitches)! I used what I think a better yarn for this style of coat. The yarn was actually cheaper, too. Not as "heavy" in weight...less likely to stretch southward which makes the sleeves become ape-like.

And
here are my Ravely notes, if you care to read about my modifications, trials and tribulations!
PHOTO ABOVE: I worked an
"applied i-cord" edge to the Fronts and along the collar the pattern said to crochet an edging, ack) which allows a very unique buttonhole application.
As you work up the Right Front, if you
skip picking up about 8 stitches along the edge of the coat, but instead knit up about 8 rows of regular i-cord, the come back to the coatwise applied i-cord technique, you create an i-cord
buttonhole loop. These buttonhole loops (or
slits if you will) can be made to accommodate any size button...in this case, a GIGANTIC button.
