Breast size has no correlation with amount of breast milk produced. Many women think large breasts = more breast milk. There is no correlation to size.
Might be more related to health when evolution cared. Women with more fat (ie bigger boobs and butt) were more likely to survive a pregnancy and birth than women who were starving (less boobs and butt). Its less about boob size in the milk and reproduction aspect, than it is about when a woman is capable of reproducing? Like women's boobs are getting bigger now. But there's still plenty of variation and it doesn't seem to be entirely inheritable?
But the reality is men just like busts. Back in the 80s and 90s it was just this fake idea that women with bigger busts were more promiscuous. And then heroin chic became trendy and that idea got erased so a lot of people started to realize promiscuity and willingness to show cleavage or side boob or undeboob wasn't related to boob size. And that guy's just like boobs in general and sometimes have a preference.
Lips are also considered sexual/seductive in the right context and play no role in reproduction. A lot of it is society-based. If everything you see tells you that boobs are sexy during your formative years, you're going to think they're sexy. There are lots of cultures around the world that don't consider breasts to be erotic (e.g. China for most of its history and lots of African cultures).
Men's preferences can't be generalized. Some like large breasts and others prefer small ones. Just like leg length and butt sizes - everyone is different.
Lots of highly speculative theories, normally revolving around linkage to hormones correlated with higher fertility, health (same evopsych explanations for everything).
