The Cosima is my favorite dress for work as it has a high neckline and is overall quite modest, it's perfect to wear to the office with a sweater or cardigan on top! I really hope they make more in the linen and georgette fabric as those are my two favorites!
While it is easy to size down because the smocking is so generous I do not recommend it as then the arm holes become a bit too small and cut into you a bit.
