The pattern is from Stephanie Japel's Fitted Knits. I read quite a bit about it before starting, I think there were a bunch of people who were disappointed with this pattern. I'm happy with how it turned out but I did make a few mods. Mostly: some waist shaping, ignoring the buttoned hip flaps and making the Box Stitch section shorter.
This is an easy, quick pattern, and it's not hard to customize to your own shape. (I'm by no means an expert). I would probably go a size up for the sleeves if I were to do this again... but other than that, I think I'll actually wear this!
