I'm into a casual-dressing girl: blue jeans and a tank top is super sexy. But the sexiest thing on a girl - when I see it I'm like, oh my God - is these little tight boxers. Don't get me wrong, g-strings are fine, but those cover a little, to where it's just enough.
If someone gives you so-called good advice, do the opposite; you can be sure it will be the right thing nine out of 10 times.
