Most of the time guys don't notice that kind of stuff (except if it is impossible not to notice it) because they are used to caring less about dressing,etc.
Now and for the past few years, there has been a new trend : boys (men) care more and more about their physical appearance and condition (I don't mean by that that they do more body building 🙄 )
Paying more attention to themselves results in paying more attention to the others...
So my answer is "not that much, but it gets better" (especially when the stuff is on a special girl 😉 )
