What do you mean by "blatantly inappropriate for wearing on out in public"? According to whom? Ask n different people and you will get n+1 different opinions on that. Also, why do you mention "Try to focus on her face" when the question is about how OP tried that and failed (and felt bad about it). You then go on to say it's on OP to not be creepy, but he can't fulfill that responsibility by communicating the issue. OP didn't manage not staring, can't communicate - sounds like the responsible thing would be to uninvite her... for her boobs. I suppose that is not what you meant? — R. Schmitz 1 min ago
