I used a finer gauge yarn than specified in the pattern so I got a 40" circumference or so instead of 42". I've knitted quite a few sweaters by this designer and I usually go for a narrower look. I also shaped the shoulders and shaped the front neckline so that it scoops about 2.5" below the back. My sleeves are also a bit narrower than specified. I finished the neckline with some purl rows.
I anticipate wearing this top quite often in the next few years.
