I recently bought a round neck dress quite a bit like this one but a bit longer. It's fine. It's only for work. But I don't like the high round neck. It needs a white collar. I don't really want a bulky shirt under it though - plus the white would show through the navy knit.
So, what I need is just a collar. I'm sure I've seen them. But a quick google isn't showing much more than mega cheap Chinese online stores.
Or I suppose something very fitted to wear under the dress would work.
Any ideas?
