It's not that you're REALLY that surprised that you're getting a bike for christmas when you've been begging your parents for several months, but the wrapping paper ramps up the antsy pants present dance to a fever pitch.
Similarly, a really good outfit on a chick is one that gives this feeling of unwrapping a present. You know it's sexy chick underneath, but it's the anticipation, not the mystery, that makes it engaging. Naked chick on its own is just "huh", or maybe even off-putting. Naked chicks are all over the place, but this is MY naked chick and I want it to come with a ribbon.
Also, you can tell a lot about a man by the kind of outfit he's likes on his women, because it reveals the things he anticipates and in turn the things that get him going beyond the sexual. Consider what a taste for doctor and nurse outfits says about a dude, what kind of person gets *anticipatory* over a medical checkup as opposed to someone who doesn't.
