lily-white

2. (American & Australian) completely honest (often negative) He's not exactly lily-white himself, so he has some nerve calling her a cheat!
3. (American & Australian) having only white people near, often because of a wish to keep black people away The black family found it difficult to feel comfortable in this lily-white, prosperous suburb.
