What this one is
You know that stretch of the year when a plain tee feels like too little and a heavy sweater feels like too much. This one sits right in the middle. It's for you if you want something with a bit of texture and structure but still light enough to wear under a jacket or on its own, cotton-alpaca blend keeping it soft against the skin without any bulk.
Your hands spend most of the time on two rhythms here: the tight, even sc of the ribbing, then the open, breathing V-stitch of the body. You'll swap hooks partway through, dropping from the 4mm to the 3.5mm, which changes the whole feel of the fabric under your fingers. Give yourself somewhere between four and six hours, worked in whatever pockets of time you've got.

Try it another way
The easiest way to make this yours is through the foundation chain. Add or subtract in pairs to keep that 2+1 multiple, and you'll get a wider or narrower shirt without touching the rest of the pattern. If you want a warmer version for cooler months, swap the cotton-alpaca blend for a wool or acrylic yarn in a similar weight, the V-stitch pattern will still show through clearly. Color-wise, this piece is lovely worked in a single soft neutral so the ribbing and V-stitch textures do the talking, but you could also work the ribbing in one shade and the body in another for a bit of contrast at the waistband. If you'd rather skip sleeves entirely, the pattern already treats them as optional, so you can leave the armholes as simple sc-finished openings for a breezier, tank-style version. And if you want a snugger neckline, work that optional third ribbing round around the neck rather than stopping at two.
