discussion Sideboob, underboob or cleavage?

[Zuze7]

Sideboob is brilliant. But I love underboob

That was the question I woke up thinking about the other day and the following were my pros and cons on the matter:
- Cleavage is the most commonly observed of the three - in the public domain. However; padding, push-up devices and smooshing together can lead to misleading presentations of shape and size.
- With sideboobs and underboobs you can be more confident that what you see is what you get.
- Sideboobs lend themselves to more covert observation.
- The underboobs look requires a certain level of perkiness which usually commends itself to the beholder.
- With underboobs there is a greater chance for slippage and revelation to occur.
For me the answer is clear: Underboobs win.
What do you think?

I propose the addition of a fourth option: downblouse.
