Say you have a fairly attractive girl. Say this girl has nice boobies. Say you're out, and you meet this girl. Now if you spend the evening staring at the girl's boobies and ignoring the rest of her, she'll probably get pissed off, and rightly so. That's all well and good, but why would she wear something super low cut and a size too small after squeezing herself into a pushup bra if she's going to get pissed off about you looking at what she goes through so much effort to show off?
