K.M., I looked at a couple of your WIWs, and this sweater will fit with your classic, simple style. You could add a matching cardigan for a cold office, if you need it, for a mad men vibe.
For me for summer when it is hot out, I prefer something looser for breathability and comfort. I have one linen t-shirt and a couple lightweight linen sweaters.
I didn't see anything linen on J Crew or Banana Republic. Eileen Fisher has a few, but they are a bit spendy. The finds appended are from shopbop. I'm just sayin' keep an eye out for a loose linen, when you are thinking ahead to summer
