Lately I have really been liking boatnecks because they are flattering to a larger bustline without showing cleavage. However it is a little nippy outside and I often want to wear something underneath for warmth, but it is hard to find something that doesn't ruin the neckline. Do other people have a good solution here? I suppose a boatneck undershirt? But that's not so easy to find is it? Am I missing something?
