Icebreaker makes great stuff, and this is a lovely wool undershirt. With the right bra, I would wear it as a t-shirt, too.
The neckline is a fairly low (not shocking) scoop, so not all of my bras are compatible with it. This matters less if worn strictly as long underwear.
The cream does allow some show-through, but it is not a fundamentally immodest garment. I've got thinner woolies that show more than this does. It's comparable to a thin cotton t-shirt for show-through. Modern American standards would not find it shocking worn on the street with an opaque bra underneath.
