Nice baselayer or standalone
Reviewing on behalf of my wife:
Good lightweight base layer or standalone shirt. Some baselayers don't like to see the light of day by themselves, this is not one of those. In our experience, Icebreaker wool tends to be soft and smooth, and this is no exception. 200 weight is nice and light without being seethrough like some 150 weight wools can be. And like all merino stuff, it doesn't smell for a long time.
The perfect shirt for my wife is slim through the body with long arms, and Icebreaker sizing seems to fit that perfectly.
